Introduzione
| Attenzione |
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.
Requisiti
Non sono necessarie librerie esterne per utilizzare questo modulo.
Installazione
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 bundled magic.mime file in your php.ini.
Esempio 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
Configurazione di Runtime
Il comportamento di queste funzioni è influenzato dalle impostazioni di php.ini.
