# Strings * Introduction * Available Methods ## Introduction Laravel includes a variety of functions for manipulating string values. Many of these functions are used by the framework itself; however, you are free to use them in your own applications if you find them convenient. ## Available Methods ### Strings __ class_basename e preg_replace_array Str::after Str::afterLast Str::apa Str::ascii Str::before Str::beforeLast Str::between Str::betweenFirst Str::camel Str::charAt Str::chopStart Str::chopEnd Str::contains Str::containsAll Str::doesntContain Str::doesntEndWith Str::doesntStartWith Str::deduplicate Str::endsWith Str::excerpt Str::finish Str::fromBase64 Str::headline Str::inlineMarkdown Str::is Str::isAscii Str::isJson Str::isUlid Str::isUrl Str::isUuid Str::kebab Str::lcfirst Str::length Str::limit Str::lower Str::markdown Str::mask Str::match Str::matchAll Str::orderedUuid Str::padBoth Str::padLeft Str::padRight Str::password Str::plural Str::pluralStudly Str::position Str::random Str::remove Str::repeat Str::replace Str::replaceArray Str::replaceFirst Str::replaceLast Str::replaceMatches Str::replaceStart Str::replaceEnd Str::reverse Str::singular Str::slug Str::snake Str::squish Str::start Str::startsWith Str::studly Str::substr Str::substrCount Str::substrReplace Str::swap Str::take Str::title Str::toBase64 Str::transliterate Str::trim Str::ltrim Str::rtrim Str::ucfirst Str::ucsplit Str::upper Str::ulid Str::unwrap Str::uuid Str::uuid7 Str::wordCount Str::wordWrap Str::words Str::wrap str trans trans_choice ### Fluent Strings after afterLast apa append ascii basename before beforeLast between betweenFirst camel charAt classBasename chopStart chopEnd contains containsAll decrypt deduplicate dirname doesntEndWith doesntStartWith encrypt endsWith exactly excerpt explode finish fromBase64 hash headline inlineMarkdown is isAscii isEmpty isNotEmpty isJson isUlid isUrl isUuid kebab lcfirst length limit lower markdown mask match matchAll isMatch newLine padBoth padLeft padRight pipe plural position prepend remove repeat replace replaceArray replaceFirst replaceLast replaceMatches replaceStart replaceEnd scan singular slug snake split squish start startsWith stripTags studly substr substrReplace swap take tap test title toBase64 toHtmlString toUri transliterate trim ltrim rtrim ucfirst ucsplit unwrap upper when whenContains whenContainsAll whenDoesntEndWith whenDoesntStartWith whenEmpty whenNotEmpty whenStartsWith whenEndsWith whenExactly whenNotExactly whenIs whenIsAscii whenIsUlid whenIsUuid whenTest wordCount words wrap ## Strings #### `__()` The `__` function translates the given translation string or translation key using your [language files](/docs/12.x/localization): 1echo __('Welcome to our application'); 2  3echo __('messages.welcome'); echo __('Welcome to our application'); echo __('messages.welcome'); If the specified translation string or key does not exist, the `__` function will return the given value. So, using the example above, the `__` function would return `messages.welcome` if that translation key does not exist. #### `class_basename()` The `class_basename` function returns the class name of the given class with the class's namespace removed: 1$class = class_basename('Foo\Bar\Baz'); 2  3// Baz $class = class_basename('Foo\Bar\Baz'); // Baz #### `e()` The `e` function runs PHP's `htmlspecialchars` function with the `double_encode` option set to `true` by default: 1echo e('foo'); 2  3// <html>foo</html> echo e('foo'); // <html>foo</html> #### `preg_replace_array()` The `preg_replace_array` function replaces a given pattern in the string sequentially using an array: 1$string = 'The event will take place between :start and :end'; 2  3$replaced = preg_replace_array('/:[a-z_]+/', ['8:30', '9:00'], $string); 4  5// The event will take place between 8:30 and 9:00 $string = 'The event will take place between :start and :end'; $replaced = preg_replace_array('/:[a-z_]+/', ['8:30', '9:00'], $string); // The event will take place between 8:30 and 9:00 #### `Str::after()` The `Str::after` method returns everything after the given value in a string. The entire string will be returned if the value does not exist within the string: 1use Illuminate\Support\Str; 2  3$slice = Str::after('This is my name', 'This is'); 4  5// ' my name' use Illuminate\Support\Str; $slice = Str::after('This is my name', 'This is'); // ' my name' #### `Str::afterLast()` The `Str::afterLast` method returns everything after the last occurrence of the given value in a string. The entire string will be returned if the value does not exist within the string: 1use Illuminate\Support\Str; 2  3$slice = Str::afterLast('App\Http\Controllers\Controller', '\\'); 4  5// 'Controller' use Illuminate\Support\Str; $slice = Str::afterLast('App\Http\Controllers\Controller', '\\'); // 'Controller' #### `Str::apa()` The `Str::apa` method converts the given string to title case following the [APA guidelines](https://apastyle.apa.org/style-grammar- guidelines/capitalization/title-case): 1use Illuminate\Support\Str; 2  3$title = Str::apa('Creating A Project'); 4  5// 'Creating a Project' use Illuminate\Support\Str; $title = Str::apa('Creating A Project'); // 'Creating a Project' #### `Str::ascii()` The `Str::ascii` method will attempt to transliterate the string into an ASCII value: 1use Illuminate\Support\Str; 2  3$slice = Str::ascii('û'); 4  5// 'u' use Illuminate\Support\Str; $slice = Str::ascii('û'); // 'u' #### `Str::before()` The `Str::before` method returns everything before the given value in a string: 1use Illuminate\Support\Str; 2  3$slice = Str::before('This is my name', 'my name'); 4  5// 'This is ' use Illuminate\Support\Str; $slice = Str::before('This is my name', 'my name'); // 'This is ' #### `Str::beforeLast()` The `Str::beforeLast` method returns everything before the last occurrence of the given value in a string: 1use Illuminate\Support\Str; 2  3$slice = Str::beforeLast('This is my name', 'is'); 4  5// 'This ' use Illuminate\Support\Str; $slice = Str::beforeLast('This is my name', 'is'); // 'This ' #### `Str::between()` The `Str::between` method returns the portion of a string between two values: 1use Illuminate\Support\Str; 2  3$slice = Str::between('This is my name', 'This', 'name'); 4  5// ' is my ' use Illuminate\Support\Str; $slice = Str::between('This is my name', 'This', 'name'); // ' is my ' #### `Str::betweenFirst()` The `Str::betweenFirst` method returns the smallest possible portion of a string between two values: 1use Illuminate\Support\Str; 2  3$slice = Str::betweenFirst('[a] bc [d]', '[', ']'); 4  5// 'a' use Illuminate\Support\Str; $slice = Str::betweenFirst('[a] bc [d]', '[', ']'); // 'a' #### `Str::camel()` The `Str::camel` method converts the given string to `camelCase`: 1use Illuminate\Support\Str; 2  3$converted = Str::camel('foo_bar'); 4  5// 'fooBar' use Illuminate\Support\Str; $converted = Str::camel('foo_bar'); // 'fooBar' #### `Str::charAt()` The `Str::charAt` method returns the character at the specified index. If the index is out of bounds, `false` is returned: 1use Illuminate\Support\Str; 2  3$character = Str::charAt('This is my name.', 6); 4  5// 's' use Illuminate\Support\Str; $character = Str::charAt('This is my name.', 6); // 's' #### `Str::chopStart()` The `Str::chopStart` method removes the first occurrence of the given value only if the value appears at the start of the string: 1use Illuminate\Support\Str; 2  3$url = Str::chopStart('https://laravel.com', 'https://'); 4  5// 'laravel.com' use Illuminate\Support\Str; $url = Str::chopStart('https://laravel.com', 'https://'); // 'laravel.com' You may also pass an array as the second argument. If the string starts with any of the values in the array then that value will be removed from string: 1use Illuminate\Support\Str; 2  3$url = Str::chopStart('http://laravel.com', ['https://', 'http://']); 4  5// 'laravel.com' use Illuminate\Support\Str; $url = Str::chopStart('http://laravel.com', ['https://', 'http://']); // 'laravel.com' #### `Str::chopEnd()` The `Str::chopEnd` method removes the last occurrence of the given value only if the value appears at the end of the string: 1use Illuminate\Support\Str; 2  3$url = Str::chopEnd('app/Models/Photograph.php', '.php'); 4  5// 'app/Models/Photograph' use Illuminate\Support\Str; $url = Str::chopEnd('app/Models/Photograph.php', '.php'); // 'app/Models/Photograph' You may also pass an array as the second argument. If the string ends with any of the values in the array then that value will be removed from string: 1use Illuminate\Support\Str; 2  3$url = Str::chopEnd('laravel.com/index.php', ['/index.html', '/index.php']); 4  5// 'laravel.com' use Illuminate\Support\Str; $url = Str::chopEnd('laravel.com/index.php', ['/index.html', '/index.php']); // 'laravel.com' #### `Str::contains()` The `Str::contains` method determines if the given string contains the given value. By default, this method is case sensitive: 1use Illuminate\Support\Str; 2  3$contains = Str::contains('This is my name', 'my'); 4  5// true use Illuminate\Support\Str; $contains = Str::contains('This is my name', 'my'); // true You may also pass an array of values to determine if the given string contains any of the values in the array: 1use Illuminate\Support\Str; 2  3$contains = Str::contains('This is my name', ['my', 'foo']); 4  5// true use Illuminate\Support\Str; $contains = Str::contains('This is my name', ['my', 'foo']); // true You may disable case sensitivity by setting the `ignoreCase` argument to `true`: 1use Illuminate\Support\Str; 2  3$contains = Str::contains('This is my name', 'MY', ignoreCase: true); 4  5// true use Illuminate\Support\Str; $contains = Str::contains('This is my name', 'MY', ignoreCase: true); // true #### `Str::containsAll()` The `Str::containsAll` method determines if the given string contains all of the values in a given array: 1use Illuminate\Support\Str; 2  3$containsAll = Str::containsAll('This is my name', ['my', 'name']); 4  5// true use Illuminate\Support\Str; $containsAll = Str::containsAll('This is my name', ['my', 'name']); // true You may disable case sensitivity by setting the `ignoreCase` argument to `true`: 1use Illuminate\Support\Str; 2  3$containsAll = Str::containsAll('This is my name', ['MY', 'NAME'], ignoreCase: true); 4  5// true use Illuminate\Support\Str; $containsAll = Str::containsAll('This is my name', ['MY', 'NAME'], ignoreCase: true); // true #### `Str::doesntContain()` The `Str::doesntContain` method determines if the given string doesn't contain the given value. By default, this method is case sensitive: 1use Illuminate\Support\Str; 2  3$doesntContain = Str::doesntContain('This is name', 'my'); 4  5// true use Illuminate\Support\Str; $doesntContain = Str::doesntContain('This is name', 'my'); // true You may also pass an array of values to determine if the given string doesn't contain any of the values in the array: 1use Illuminate\Support\Str; 2  3$doesntContain = Str::doesntContain('This is name', ['my', 'foo']); 4  5// true use Illuminate\Support\Str; $doesntContain = Str::doesntContain('This is name', ['my', 'foo']); // true You may disable case sensitivity by setting the `ignoreCase` argument to `true`: 1use Illuminate\Support\Str; 2  3$doesntContain = Str::doesntContain('This is name', 'MY', ignoreCase: true); 4  5// true use Illuminate\Support\Str; $doesntContain = Str::doesntContain('This is name', 'MY', ignoreCase: true); // true #### `Str::deduplicate()` The `Str::deduplicate` method replaces consecutive instances of a character with a single instance of that character in the given string. By default, the method deduplicates spaces: 1use Illuminate\Support\Str; 2  3$result = Str::deduplicate('The Laravel Framework'); 4  5// The Laravel Framework use Illuminate\Support\Str; $result = Str::deduplicate('The Laravel Framework'); // The Laravel Framework You may specify a different character to deduplicate by passing it in as the second argument to the method: 1use Illuminate\Support\Str; 2  3$result = Str::deduplicate('The---Laravel---Framework', '-'); 4  5// The-Laravel-Framework use Illuminate\Support\Str; $result = Str::deduplicate('The---Laravel---Framework', '-'); // The-Laravel-Framework #### `Str::doesntEndWith()` The `Str::doesntEndWith` method determines if the given string doesn't end with the given value: 1use Illuminate\Support\Str; 2  3$result = Str::doesntEndWith('This is my name', 'dog'); 4  5// true use Illuminate\Support\Str; $result = Str::doesntEndWith('This is my name', 'dog'); // true You may also pass an array of values to determine if the given string doesn't end with any of the values in the array: 1use Illuminate\Support\Str; 2  3$result = Str::doesntEndWith('This is my name', ['this', 'foo']); 4  5// true 6  7$result = Str::doesntEndWith('This is my name', ['name', 'foo']); 8  9// false use Illuminate\Support\Str; $result = Str::doesntEndWith('This is my name', ['this', 'foo']); // true $result = Str::doesntEndWith('This is my name', ['name', 'foo']); // false #### `Str::doesntStartWith()` The `Str::doesntStartWith` method determines if the given string doesn't begin with the given value: 1use Illuminate\Support\Str; 2  3$result = Str::doesntStartWith('This is my name', 'That'); 4  5// true use Illuminate\Support\Str; $result = Str::doesntStartWith('This is my name', 'That'); // true If an array of possible values is passed, the `doesntStartWith` method will return `true` if the string doesn't begin with any of the given values: 1$result = Str::doesntStartWith('This is my name', ['What', 'That', 'There']); 2  3// true $result = Str::doesntStartWith('This is my name', ['What', 'That', 'There']); // true #### `Str::endsWith()` The `Str::endsWith` method determines if the given string ends with the given value: 1use Illuminate\Support\Str; 2  3$result = Str::endsWith('This is my name', 'name'); 4  5// true use Illuminate\Support\Str; $result = Str::endsWith('This is my name', 'name'); // true You may also pass an array of values to determine if the given string ends with any of the values in the array: 1use Illuminate\Support\Str; 2  3$result = Str::endsWith('This is my name', ['name', 'foo']); 4  5// true 6  7$result = Str::endsWith('This is my name', ['this', 'foo']); 8  9// false use Illuminate\Support\Str; $result = Str::endsWith('This is my name', ['name', 'foo']); // true $result = Str::endsWith('This is my name', ['this', 'foo']); // false #### `Str::excerpt()` The `Str::excerpt` method extracts an excerpt from a given string that matches the first instance of a phrase within that string: 1use Illuminate\Support\Str; 2  3$excerpt = Str::excerpt('This is my name', 'my', [ 4 'radius' => 3 5]); 6  7// '...is my na...' use Illuminate\Support\Str; $excerpt = Str::excerpt('This is my name', 'my', [ 'radius' => 3 ]); // '...is my na...' The `radius` option, which defaults to `100`, allows you to define the number of characters that should appear on each side of the truncated string. In addition, you may use the `omission` option to define the string that will be prepended and appended to the truncated string: 1use Illuminate\Support\Str; 2  3$excerpt = Str::excerpt('This is my name', 'name', [ 4 'radius' => 3, 5 'omission' => '(...) ' 6]); 7  8// '(...) my name' use Illuminate\Support\Str; $excerpt = Str::excerpt('This is my name', 'name', [ 'radius' => 3, 'omission' => '(...) ' ]); // '(...) my name' #### `Str::finish()` The `Str::finish` method adds a single instance of the given value to a string if it does not already end with that value: 1use Illuminate\Support\Str; 2  3$adjusted = Str::finish('this/string', '/'); 4  5// this/string/ 6  7$adjusted = Str::finish('this/string/', '/'); 8  9// this/string/ use Illuminate\Support\Str; $adjusted = Str::finish('this/string', '/'); // this/string/ $adjusted = Str::finish('this/string/', '/'); // this/string/ #### `Str::fromBase64()` The `Str::fromBase64` method decodes the given Base64 string: 1use Illuminate\Support\Str; 2  3$decoded = Str::fromBase64('TGFyYXZlbA=='); 4  5// Laravel use Illuminate\Support\Str; $decoded = Str::fromBase64('TGFyYXZlbA=='); // Laravel #### `Str::headline()` The `Str::headline` method will convert strings delimited by casing, hyphens, or underscores into a space delimited string with each word's first letter capitalized: 1use Illuminate\Support\Str; 2  3$headline = Str::headline('steve_jobs'); 4  5// Steve Jobs 6  7$headline = Str::headline('EmailNotificationSent'); 8  9// Email Notification Sent use Illuminate\Support\Str; $headline = Str::headline('steve_jobs'); // Steve Jobs $headline = Str::headline('EmailNotificationSent'); // Email Notification Sent #### `Str::inlineMarkdown()` The `Str::inlineMarkdown` method converts GitHub flavored Markdown into inline HTML using [CommonMark](https://commonmark.thephpleague.com/). However, unlike the `markdown` method, it does not wrap all generated HTML in a block-level element: 1use Illuminate\Support\Str; 2  3$html = Str::inlineMarkdown('**Laravel**'); 4  5// Laravel use Illuminate\Support\Str; $html = Str::inlineMarkdown('**Laravel**'); // Laravel #### Markdown Security By default, Markdown supports raw HTML, which will expose Cross-Site Scripting (XSS) vulnerabilities when used with raw user input. As per the [CommonMark Security documentation](https://commonmark.thephpleague.com/security/), you may use the `html_input` option to either escape or strip raw HTML, and the `allow_unsafe_links` option to specify whether to allow unsafe links. If you need to allow some raw HTML, you should pass your compiled Markdown through an HTML Purifier: 1use Illuminate\Support\Str; 2  3Str::inlineMarkdown('Inject: ', [ 4 'html_input' => 'strip', 5 'allow_unsafe_links' => false, 6]); 7  8// Inject: alert("Hello XSS!"); use Illuminate\Support\Str; Str::inlineMarkdown('Inject: ', [ 'html_input' => 'strip', 'allow_unsafe_links' => false, ]); // Inject: alert("Hello XSS!"); #### `Str::is()` The `Str::is` method determines if a given string matches a given pattern. Asterisks may be used as wildcard values: 1use Illuminate\Support\Str; 2  3$matches = Str::is('foo*', 'foobar'); 4  5// true 6  7$matches = Str::is('baz*', 'foobar'); 8  9// false use Illuminate\Support\Str; $matches = Str::is('foo*', 'foobar'); // true $matches = Str::is('baz*', 'foobar'); // false You may disable case sensitivity by setting the `ignoreCase` argument to `true`: 1use Illuminate\Support\Str; 2  3$matches = Str::is('*.jpg', 'photo.JPG', ignoreCase: true); 4  5// true use Illuminate\Support\Str; $matches = Str::is('*.jpg', 'photo.JPG', ignoreCase: true); // true #### `Str::isAscii()` The `Str::isAscii` method determines if a given string is 7 bit ASCII: 1use Illuminate\Support\Str; 2  3$isAscii = Str::isAscii('Taylor'); 4  5// true 6  7$isAscii = Str::isAscii('ü'); 8  9// false use Illuminate\Support\Str; $isAscii = Str::isAscii('Taylor'); // true $isAscii = Str::isAscii('ü'); // false #### `Str::isJson()` The `Str::isJson` method determines if the given string is valid JSON: 1use Illuminate\Support\Str; 2  3$result = Str::isJson('[1,2,3]'); 4  5// true 6  7$result = Str::isJson('{"first": "John", "last": "Doe"}'); 8  9// true 10  11$result = Str::isJson('{first: "John", last: "Doe"}'); 12  13// false use Illuminate\Support\Str; $result = Str::isJson('[1,2,3]'); // true $result = Str::isJson('{"first": "John", "last": "Doe"}'); // true $result = Str::isJson('{first: "John", last: "Doe"}'); // false #### `Str::isUrl()` The `Str::isUrl` method determines if the given string is a valid URL: 1use Illuminate\Support\Str; 2  3$isUrl = Str::isUrl('http://example.com'); 4  5// true 6  7$isUrl = Str::isUrl('laravel'); 8  9// false use Illuminate\Support\Str; $isUrl = Str::isUrl('http://example.com'); // true $isUrl = Str::isUrl('laravel'); // false The `isUrl` method considers a wide range of protocols as valid. However, you may specify the protocols that should be considered valid by providing them to the `isUrl` method: 1$isUrl = Str::isUrl('http://example.com', ['http', 'https']); $isUrl = Str::isUrl('http://example.com', ['http', 'https']); #### `Str::isUlid()` The `Str::isUlid` method determines if the given string is a valid ULID: 1use Illuminate\Support\Str; 2  3$isUlid = Str::isUlid('01gd6r360bp37zj17nxb55yv40'); 4  5// true 6  7$isUlid = Str::isUlid('laravel'); 8  9// false use Illuminate\Support\Str; $isUlid = Str::isUlid('01gd6r360bp37zj17nxb55yv40'); // true $isUlid = Str::isUlid('laravel'); // false #### `Str::isUuid()` The `Str::isUuid` method determines if the given string is a valid UUID: 1use Illuminate\Support\Str; 2  3$isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de'); 4  5// true 6  7$isUuid = Str::isUuid('laravel'); 8  9// false use Illuminate\Support\Str; $isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de'); // true $isUuid = Str::isUuid('laravel'); // false You may also validate that the given UUID matches a UUID specification by version (1, 3, 4, 5, 6, 7, or 8): 1use Illuminate\Support\Str; 2  3$isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de', version: 4); 4  5// true 6  7$isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de', version: 1); 8  9// false use Illuminate\Support\Str; $isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de', version: 4); // true $isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de', version: 1); // false #### `Str::kebab()` The `Str::kebab` method converts the given string to `kebab-case`: 1use Illuminate\Support\Str; 2  3$converted = Str::kebab('fooBar'); 4  5// foo-bar use Illuminate\Support\Str; $converted = Str::kebab('fooBar'); // foo-bar #### `Str::lcfirst()` The `Str::lcfirst` method returns the given string with the first character lowercased: 1use Illuminate\Support\Str; 2  3$string = Str::lcfirst('Foo Bar'); 4  5// foo Bar use Illuminate\Support\Str; $string = Str::lcfirst('Foo Bar'); // foo Bar #### `Str::length()` The `Str::length` method returns the length of the given string: 1use Illuminate\Support\Str; 2  3$length = Str::length('Laravel'); 4  5// 7 use Illuminate\Support\Str; $length = Str::length('Laravel'); // 7 #### `Str::limit()` The `Str::limit` method truncates the given string to the specified length: 1use Illuminate\Support\Str; 2  3$truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20); 4  5// The quick brown fox... use Illuminate\Support\Str; $truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20); // The quick brown fox... You may pass a third argument to the method to change the string that will be appended to the end of the truncated string: 1$truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20, ' (...)'); 2  3// The quick brown fox (...) $truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20, ' (...)'); // The quick brown fox (...) If you would like to preserve complete words when truncating the string, you may utilize the `preserveWords` argument. When this argument is `true`, the string will be truncated to the nearest complete word boundary: 1$truncated = Str::limit('The quick brown fox', 12, preserveWords: true); 2  3// The quick... $truncated = Str::limit('The quick brown fox', 12, preserveWords: true); // The quick... #### `Str::lower()` The `Str::lower` method converts the given string to lowercase: 1use Illuminate\Support\Str; 2  3$converted = Str::lower('LARAVEL'); 4  5// laravel use Illuminate\Support\Str; $converted = Str::lower('LARAVEL'); // laravel #### `Str::markdown()` The `Str::markdown` method converts GitHub flavored Markdown into HTML using [CommonMark](https://commonmark.thephpleague.com/): 1use Illuminate\Support\Str; 2  3$html = Str::markdown('# Laravel'); 4  5//

Laravel

6  7$html = Str::markdown('# Taylor Otwell', [ 8 'html_input' => 'strip', 9]); 10  11//

Taylor Otwell

use Illuminate\Support\Str; $html = Str::markdown('# Laravel'); //

Laravel

$html = Str::markdown('# Taylor Otwell', [ 'html_input' => 'strip', ]); //

Taylor Otwell

#### Markdown Security By default, Markdown supports raw HTML, which will expose Cross-Site Scripting (XSS) vulnerabilities when used with raw user input. As per the [CommonMark Security documentation](https://commonmark.thephpleague.com/security/), you may use the `html_input` option to either escape or strip raw HTML, and the `allow_unsafe_links` option to specify whether to allow unsafe links. If you need to allow some raw HTML, you should pass your compiled Markdown through an HTML Purifier: 1use Illuminate\Support\Str; 2  3Str::markdown('Inject: ', [ 4 'html_input' => 'strip', 5 'allow_unsafe_links' => false, 6]); 7  8//

Inject: alert("Hello XSS!");

use Illuminate\Support\Str; Str::markdown('Inject: ', [ 'html_input' => 'strip', 'allow_unsafe_links' => false, ]); //

If the substring does not exist in the given string, `false` is returned: 1use Illuminate\Support\Str; 2  3$position = Str::position('Hello, World!', 'Hello'); 4  5// 0 6  7$position = Str::position('Hello, World!', 'W'); 8  9// 7 use Illuminate\Support\Str; $position = Str::position('Hello, World!', 'Hello'); // 0 $position = Str::position('Hello, World!', 'W'); // 7 #### `Str::random()` The `Str::random` method generates a random string of the specified length. This function uses PHP's `random_bytes` function: 1use Illuminate\Support\Str; 2  3$random = Str::random(40); use Illuminate\Support\Str; $random = Str::random(40); During testing, it may be useful to "fake" the value that is returned by the `Str::random` method. To accomplish this, you may use the `createRandomStringsUsing` method: 1Str::createRandomStringsUsing(function () { 2 return 'fake-random-string'; 3}); Str::createRandomStringsUsing(function () { return 'fake-random-string'; }); To instruct the `random` method to return to generating random strings normally, you may invoke the `createRandomStringsNormally` method: 1Str::createRandomStringsNormally(); Str::createRandomStringsNormally(); #### `Str::remove()` The `Str::remove` method removes the given value or array of values from the string: 1use Illuminate\Support\Str; 2  3$string = 'Peter Piper picked a peck of pickled peppers.'; 4  5$removed = Str::remove('e', $string); 6  7// Ptr Pipr pickd a pck of pickld ppprs. use Illuminate\Support\Str; $string = 'Peter Piper picked a peck of pickled peppers.'; $removed = Str::remove('e', $string); // Ptr Pipr pickd a pck of pickld ppprs.

\n"); /* The quick brown fox
jumped over the lazy
dog. */ #### `Str::words()` The `Str::words` method limits the number of words in a string. An additional string may be passed to this method via its third argument to specify which string should be appended to the end of the truncated string: 1use Illuminate\Support\Str; 2  3return Str::words('Perfectly balanced, as all things should be.', 3, ' >>>'); 4  5// Perfectly balanced, as >>> use Illuminate\Support\Str; return Str::words('Perfectly balanced, as all things should be.', 3, ' >>>'); // Perfectly balanced, as >>> #### `Str::wrap()` The `Str::wrap` method wraps the given string with an additional string or pair of strings: 1use Illuminate\Support\Str; 2  3Str::wrap('Laravel', '"'); 4  5// "Laravel" 6  7Str::wrap('is', before: 'This ', after: ' Laravel!'); 8  9// This is Laravel! use Illuminate\Support\Str; Str::wrap('Laravel', '"'); // "Laravel" Str::wrap('is', before: 'This ', after: ' Laravel!'); // This is Laravel! #### `str()` The `str` function returns a new `Illuminate\Support\Stringable` instance of the given string. This function is equivalent to the `Str::of` method: 1$string = str('Taylor')->append(' Otwell'); 2  3// 'Taylor Otwell' $string = str('Taylor')->append(' Otwell'); // 'Taylor Otwell' If no argument is provided to the `str` function, the function returns an instance of `Illuminate\Support\Str`: 1$snake = str()->snake('FooBar'); 2  3// 'foo_bar' $snake = str()->snake('FooBar'); // 'foo_bar' #### `trans()` The `trans` function translates the given translation key using your [language files](/docs/12.x/localization): 1echo trans('messages.welcome'); echo trans('messages.welcome'); If the specified translation key does not exist, the `trans` function will return the given key. So, using the example above, the `trans` function would return `messages.welcome` if the translation key does not exist. #### `trans_choice()` The `trans_choice` function translates the given translation key with inflection: 1echo trans_choice('messages.notifications', $unreadCount); echo trans_choice('messages.notifications', $unreadCount); If the specified translation key does not exist, the `trans_choice` function will return the given key. So, using the example above, the `trans_choice` function would return `messages.notifications` if the translation key does not exist. ## Fluent Strings Fluent strings provide a more fluent, object-oriented interface for working with string values, allowing you to chain multiple string operations together using a more readable syntax compared to traditional string operations. #### `after` The `after` method returns everything after the given value in a string. The entire string will be returned if the value does not exist within the string: 1use Illuminate\Support\Str; 2  3$slice = Str::of('This is my name')->after('This is'); 4  5// ' my name' use Illuminate\Support\Str; $slice = Str::of('This is my name')->after('This is'); // ' my name' #### `afterLast` The `afterLast` method returns everything after the last occurrence of the given value in a string.
