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.

Fluent Strings

Strings

`__()`

The __ function translates the given translation string or translation key using your language files:

1echo __('Welcome to our application');
2 
3echo __('messages.welcome');1echo __('Welcome to our application');
2 
3echo __('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$class = class_basename('Foo\Bar\Baz');
2 
3// Baz1$class = class_basename('Foo\Bar\Baz');
2 
3// Baz

`e()`

The e function runs PHP's htmlspecialchars function with the double_encode option set to true by default:

1echo e('<html>foo</html>');
2 
3// &lt;html&gt;foo&lt;/html&gt;1echo e('<html>foo</html>');
2 
3// &lt;html&gt;foo&lt;/html&gt;

`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'], $string);
4 
5// The event will take place between 8:30 and 9:001$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

`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$slice = Str::after('This is my name', 'This is');
4 
5// ' my name'1use Illuminate\Support\Str;
2 
3$slice = Str::after('This is my name', 'This is');
4 
5// ' 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$slice = Str::afterLast('App\Http\Controllers\Controller', '\\');
4 
5// 'Controller'1use Illuminate\Support\Str;
2 
3$slice = Str::afterLast('App\Http\Controllers\Controller', '\\');
4 
5// 'Controller'

`Str::ascii()`

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

1use Illuminate\Support\Str;
2 
3$slice = Str::ascii('û');
4 
5// 'u'1use Illuminate\Support\Str;
2 
3$slice = Str::ascii('û');
4 
5// 'u'

`Str::before()`

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

1use Illuminate\Support\Str;
2 
3$slice = Str::before('This is my name', 'my name');
4 
5// 'This is '1use Illuminate\Support\Str;
2 
3$slice = Str::before('This is my name', 'my name');
4 
5// 'This is '

`Str::beforeLast()`

4 
5// 'This '1use Illuminate\Support\Str;
2 
3$slice = Str::beforeLast('This is my name', 'is');
4 
5// 'This '

`Str::between()`

4 
5// ' is my '1use Illuminate\Support\Str;
2 
3$slice = Str::between('This is my name', 'This', 'name');
4 
5// ' 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$slice = Str::betweenFirst('[a] bc [d]', '[', ']');
4 
5// 'a'1use Illuminate\Support\Str;
2 
3$slice = Str::betweenFirst('[a] bc [d]', '[', ']');
4 
5// 'a'

`Str::camel()`

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

1use Illuminate\Support\Str;
2 
3$converted = Str::camel('foo_bar');
4 
5// fooBar1use Illuminate\Support\Str;
2 
3$converted = Str::camel('foo_bar');
4 
5// fooBar

`Str::contains()`

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

1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', 'my');
4 
5// true1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', 'my');
4 
5// 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$contains = Str::contains('This is my name', ['my', 'foo']);
4 
5// true1use Illuminate\Support\Str;
2 
3$contains = Str::contains('This is my name', ['my', 'foo']);
4 
5// 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

4 
5// true1use Illuminate\Support\Str;
2 
3$result = Str::endsWith('This is my name', 'name');
4 
5// 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// false1use 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

`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$excerpt = Str::excerpt('This is my name', 'my', [
4    'radius' => 3
5]);
6 
7// '...is my na...'1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'my', [
4    'radius' => 3
5]);
6 
7// '...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$excerpt = Str::excerpt('This is my name', 'name', [
4    'radius' => 3,
5    'omission' => '(...) '
6]);
7 
8// '(...) my name'1use Illuminate\Support\Str;
2 
3$excerpt = Str::excerpt('This is my name', 'name', [
4    'radius' => 3,
5    'omission' => '(...) '
6]);
7 
8// '(...) 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/1use Illuminate\Support\Str;
2 
3$adjusted = Str::finish('this/string', '/');
4 
5// this/string/
6

4 
5// Steve Jobs
6 
7$headline = Str::headline('EmailNotificationSent');
8 
9// Email Notification Sent1use Illuminate\Support\Str;

5// 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');

5// foo Bar1use Illuminate\Support\Str;
2 
3$string = Str::lcfirst('Foo Bar');
4 
5// 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');

`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:

1use Illuminate\Support\Str;
2 
3$string = Str::mask('[email protected]', '*', 3);
4 
5// tay***************1use Illuminate\Support\Str;
2 
3$string = Str::mask('[email protected]', '*', 3);

7$plural = Str::plural('child');
8 
9// children

You may provide an integer as a second argument to the function to retrieve the singular or plural form of the string:

1use Illuminate\Support\Str;
2 
3$plural = Str::plural('child', 2);
4 
5// children
6 
7$singular = Str::plural('child', 1);

6 
7$singular = Str::plural('child', 1);
8 
9// child

`Str::pluralStudly()`

The Str::pluralStudly method converts a singular word string formatted in studly caps case to its plural form. This function supports any of the languages support by Laravel's pluralizer:

4 
5// 0
6 
7$position = Str::position('Hello, World!', 'W');
8 
9// 71use Illuminate\Support\Str;

2 
3$random = Str::random(40);1use Illuminate\Support\Str;
2 
3$random = Str::random(40);

`Str::remove()`

6 
7// Ptr Pipr pickd a pck of pickld ppprs.1use Illuminate\Support\Str;
2 
3$string = 'Peter Piper picked a peck of pickled peppers.';
4
