String manipulation, leveled up! -- by, Chris Kankiewicz (@PHLAK)


Twine is a simple string manipulation library with an expressive, fluent syntax.


Install with Composer

composer require phlak/twine

Getting Started

First, import Twine:

use PHLAK\Twine;

Then instantiate a Twine object by newing up a Twine\Str object and passing your string as the first parameter.

$string = new Twine\Str('john pinkerton');

You may also instantiate a Twine\Str object statically via the make() method.

$string = Twine\Str::make('john pinkerton');

Or use the global str() helper method. The method takes a string as the only parameter and returns a Twine\Str object.

$string = str('john pinkerton');

Once you have a concrete Twine\Str instance you may treat it like any other string. This includes echoing it or using any of PHP's built in string functions against it.

echo $string; // Echos 'john pinkerton'

str_shuffle($string) // Returns something like 'enoipo ktnjhnr'

strlen($string); // Returns 14

The strength of Twine, however comes from it's built-in methods.

$string->echo(); // Echos 'john pinkerton'
$string->shuffle(); // Returns something like 'enoipo ktnjhnr'
$string->length(); // Returns 14

// or some more interesting methods

$string->reverse(); // Returns 'notreknip nhoj'
$string->contains('pink'); // Returns true
$stting->replace('pink', 'purple'); // Returns 'john purpleton'
$string->snakeCase(); // Returns 'john_pinkerton'

At this point you're ready to start using Twine by calling any of its many built in methods.

Available Methods


Method Chaining

A Twine string can be manipulated fluently by chaining methods. Here are a few example chains:

Perform a substring comparison:

$string = new Twine\Str('john pinkerton');

$string->substring(5, 4)->equals('pink'); // Returns true

Encode a file in compliance with RFC 2045.

$string = new Twine\Str(file_get_contents('garbage.bin'));

$string->base64()->wrap(76, "\r\n", Twine\Config\Wrap::HARD);
