LXXI. Mimetype Functions

Wstęp

Ostrzeżenie

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.

Wymagania

Do zbudowania tego rozszerzenia nie są wymagane żadne zewnętrzne biblioteki.

Instalacja

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.

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

Notatka: 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.

Przykład 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
