LVII. Mimetype Functions

Úvod

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.

Požadavky

Tyto funkce jsou k dispozici jako součást standardního modulu, který je vždy dostupný.

Instalace

The extension needs a copy of the magic.mime as distributed with the file command. This file also part of most recent Linux distributions and usually stored in the /usr/share/misc directory.

Konfigurace běhu

Chování těchto funkcí je ovlivněno nastavením parametrů v php.ini.
