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 Before this time, fileinfo was a PECL extension but is no longer maintained there.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.
