LXXXVII. Mimetype Functions
Úvod
Varování |
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.
Požadavky
Tyto funkce jsou k dispozici jako součást standardního modulu, který je vždy dostupný.
Instalace
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.
Poznámka: The configure option has been changed from
--enable-mime-magic
to--with-mime-magic
since PHP 4.3.2
Poznámka: 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.
Remember to substitute the $PHP_INSTALL_DIR for your actual path to PHP in the above example. e.g. c:\php
Konfigurace běhu
Chování těchto funkcí je ovlivněno nastavením parametrů v php.ini.
