A fast PHP slug generator and transliteration library, started as a PHP port of
URLify.js
from the Django project.

Symbols it cannot transliterate it can omit or replace with a specified character.

Installation

Install the latest version with:

$ composer require jbroadway/urlify

Usage

First, include Composer’s autoloader:

require_once 'vendor/autoload.php';

To generate slugs for URLs:

<?php

echo URLify::slug (' J\'étudie le français ');
// "jetudie-le-francais"

echo URLify::slug ('Lo siento, no hablo español.');
// "lo-siento-no-hablo-espanol"

To generate slugs for file names:

<?php

echo URLify::filter ('фото.jpg', 60, "", true);
// "foto.jpg"

To simply transliterate characters:

<?php

echo URLify::downcode ('J\'étudie le français');
// "J'etudie le francais"

echo URLify::downcode ('Lo siento, no hablo español.');
// "Lo siento, no hablo espanol."

/* Or use transliterate() alias: */

echo URLify::transliterate ('Lo siento, no hablo español.');
// "Lo siento, no hablo espanol."

To extend the character list:

<?php

URLify::add_chars ([
	'¿' => '?', '®' => '(r)', '¼' => '1/4',
	'½' => '1/2', '¾' => '3/4', '¶' => 'P'
]);

echo URLify::downcode ('¿ ® ¼ ¼ ¾ ¶');
// "? (r) 1/2 1/2 3/4 P"

To extend the list of words to remove:

<?php

URLify::remove_words (['remove', 'these', 'too']);

To prioritize a certain language map:

<?php

echo URLify::filter ('Ägypten und Österreich besitzen wie üblich ein Übermaß an ähnlich öligen Attachés', 60, 'de');
// "aegypten-und-oesterreich-besitzen-wie-ueblich-ein-uebermass-aehnlich-oeligen-attaches"

echo URLify::filter ('Cağaloğlu, çalıştığı, müjde, lazım, mahkûm', 60, 'tr');
// "cagaloglu-calistigi-mujde-lazim-mahkum"

Please note that the “ü” is transliterated to “ue” in the first case, whereas it results in a simple “u” in the latter.
