Warning

Mimetype extensions has been removed from PHP 5.3.0 in favor of Fileinfo.

You must compile PHP with the configure switch --with-mime-magic to get support for mime-type functions. The extension needs a copy of the simplified `magic` file that is distributed with the Apache httpd.

Note:

This extension is not capable of handling the fully decorated `magic` file that generally comes with standard Linux distro's and is supposed to be used with recent versions of `file` command.

Note: Note to Win32 Users

In order to use this module on a Windows environment, you must set the path to the bundled `magic.mime` file in your `php.ini`.

``````mime_magic.magicfile = "\$PHP_INSTALL_DIR\magic.mime"
``````

Remember to substitute the `\$PHP_INSTALL_DIR` for your actual path to PHP in the above example. e.g. `c:\php`
