# LXXXIV. Mimetype Functions

# ��

警告
This extension has been deprecated as the PECL extension Fileinfo provides the same functionality (and more) in a much cleaner way.

The functions in this module try to guess the content type and encoding of a file by looking for certain magic byte sequences at specific positions within the file. While this is not a bullet proof approach the heuristics used do a very good job.

This extension is derived from Apache mod_mime_magic, which is itself based on the `file` command maintained by Ian F. Darwin. See the source code for further historic and copyright information.

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.

> 注: The configure option has been changed from --enable-mime-magic to --with-mime-magic since PHP 4.3.2

> 注: 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 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`.

> 範例 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`
