This extension is enabled by default as of PHP 5.3.0. Before this time, fileinfo was a PECL extension but is no longer maintained there. However, versions prior to 5.3+ may use the » discontinued PECL extension.

Windows users must include the bundled php_fileinfo.dll DLL file in php.ini to enable this extension.

The libmagic library is bundled with PHP, but includes PHP specific changes. A patch against libmagic named libmagic.patch is maintained and may be found within the PHP fileinfo extensions source.
