preg_replace_array()
The preg_replace_array function replaces a given pattern in the string sequentially using an array:

$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:

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:

use Illuminate\Support\Str;

$slice = Str::afterLast('App\Http\Controllers\Controller', '\\');

// 'Controller'

Str::ascii()
The Str::ascii method will attempt to transliterate the string into an ASCII value:

use Illuminate\Support\Str;

$slice = Str::ascii('û');

// 'u'

Str::before()
The Str::before method returns everything before the given value in a string:

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:

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:

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:

use Illuminate\Support\Str;

$slice = Str::betweenFirst('[a] bc [d]', '[', ']');

// 'a

'

Str::camel()
The Str::camel method converts the given string to camelCase:

use Illuminate\Support\Str;

$converted = Str::camel('foo_bar');

// fooBar

Str::contains()
The Str::contains method determines if the given string contains the given value. This method is case sensitive:

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:

use Illuminate\Support\Str;

$contains = Str::contains('This is my name', ['my', 'foo']);

// true

Str::containsAll()
The Str::containsAll method determines if the given string contains all of the values in a given array:

use Illuminate\Support\Str;

// true

Str::endsWith()
The Str::endsWith method determines if the given string ends with the given value:

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:

use Illuminate\Support\Str;

$result = Str::endsWith('This is my name', ['name', 'foo']);

// true

$result = Str::endsWith('This is my name', ['this', 'foo']);

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:

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:

use Illuminate\Support\Str;

$html = Str::inlineMarkdown('**Laravel**');

// <strong>Laravel</strong>

Str::is()
The Str::is method determines if a given string matches a given pattern. Asterisks may be used as wildcard values:

// true

$isAscii = Str::isAscii('ü');

// false

Str::isJson()
The Str::isJson method determines if the given string is valid JSON:

use Illuminate\Support\Str;

$result = Str::isJson('[1,2,3]');

// true

$result = Str::isJson('{"first": "John", "last": "Doe"}');

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:

use Illuminate\Support\Str;

$string = Str::lcfirst('Foo Bar');

// foo Bar

Str::length()
The Str::length method returns the length of the given string:

use Illuminate\Support\Str;

$length = Str::length('Laravel');

// 7

Str::limit()
The Str::limit method truncates the given string to the specified length:

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:

use Illuminate\Support\Str;

$truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20, ' (...)');

// The quick brown fox (...)

Str::lower()
The Str::lower method converts the given string to lowercase:

use Illuminate\Support\Str;

$converted = Str::lower('LARAVEL');

$html = Str::markdown('# Laravel');

// <h1>Laravel</h1>

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

// <h1>Taylor Otwell</h1>

Str::mask()
The Str::mask method masks a portion of a string with a repeated character, and may be used to obfuscate segments of strings such as email addresses and phone numbers:

use Illuminate\Support\Str;

$string = Str::mask('taylor@example.com', '*', 3);

// tay***************

If needed, you provide a negative number as the third argument to the mask method, which will instruct the method to begin masking at the given distance from the end of the string:

$string = Str::mask('taylor@example.com', '*', -15, 3);

// tay***@example.com

Str::orderedUuid()
The Str::orderedUuid method generates a "timestamp first" UUID that may be efficiently stored in an indexed database column. Each UUID that is generated using this method will be sorted after UUIDs previously generated using the method:

use Illuminate\Support\Str;

return (string) Str::orderedUuid();

Str::padBoth()
The Str::padBoth method wraps PHP's str_pad function, padding both sides of a string with another string until the final string reaches a desired length:

$padded = Str::padBoth('James', 10);

// '  James  

'

Str::padLeft()
The Str::padLeft method wraps PHP's str_pad function, padding the left side of a string with another string until the final string reaches a desired length:

$padded = Str::padRight('James', 10);

// 'James  

'
