The Symfony Polyfill / Intl Grapheme Component

Warning: You are browsing the documentation for Symfony 2.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

This component provides a partial, native PHP implementation of the grapheme_* functions to users who run PHP versions without the intl extension.

Installation

1
$ composer require symfony/polyfill-intl-grapheme

Alternatively, you can clone the https://github.com/symfony/polyfill-intl-grapheme repository.

Note

If you install this component outside of a Symfony application, you must require the vendor/autoload.php file in your code to enable the class autoloading mechanism provided by Composer. Read this article for more details.

Usage

Once this component is installed in your application, you can use the following constants and functions, no matter if the PHP intl extension is installed or not in your server.

Provided Constants

  • GRAPHEME_EXTR_COUNT (value = 0)
  • GRAPHEME_EXTR_MAXBYTES (value = 1)
  • GRAPHEME_EXTR_MAXCHARS (value = 2)
