LVII_ Mimetype Functions

Introducción

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 derivated from Apache mod_mime_magic, which is itself based on the file command maintaind by Ian F_ Darwin_ See the source code for further historic and copyright information_

Instalación

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_

Nota: The configure option has been changed from __enable_mime_magic to __with_mime_magic since PHP 4_3_2

Nota: 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 bundeld magic_mime file in your php_ini_
Ejemplo 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
