Installation

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.

Example #1 Setting the path to magic.mime

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
