Liste des sections du fichier php.ini

Cette liste inclut les sections du php.ini que vous pouvez ajuster pour configurer votre PHP selon l'hôte virtuel ou le chemin. Ces sections sont optionnelles.

Ces sections n'affectent pas directement PHP. Elles sont utilisées pour grouper les autres directives de configuration du php.ini et pour les appliquer à un hôte ou à un chemin particulier.

Ces sections ne sont utilisées qu'en mode CGI/FastCGI et elles ne peuvent définir des extensions et des directives zend_extension.

Nom Modifiable Historique

Voici un éclaircissement sur l'utilisation des directives de configuration.

Cette section vous permet de définir un jeu de directives du php.ini qui prendront effet quand un script sera lancé depuis le chemin spécifié.

In [HOST=...] one should use only the 1st server name from the list of server names.

I.E. if you have
server_name example.com, example2.com;
and will use www.example.com in a browser,
use [HOST=example.com] in php.ini for both addresses.

PHP looks not at the HOST request header (as I expected), but at the SERVER_NAME parameter (which by default is the 1st from the list of names, no matter what the HOST is).

Sorry for the note. I've read some bad tutorials.
The correct syntax is : directive = 'value'
not a thing like : php_value[directive] = "somevalue"

this HOST and PATH sections doesn't seems to work in php.ini under apache 2.4 with php-fpm 7.1.16 for directive php_value or php_admin_value open_basedir or include_path.
phpinfo() says "none" in master and local values.

If you have a system which uses separated PHP inis for loading extensions (Debian, Fedora and most other distributions do so), [PATH=] or [HOST=] will prevent loading extensions defined in those ini files (extension= and zend_extension=).

I had some headache, when I added a hosts.ini to /etc/php5/cgi/conf.d (Debians default), where I wanted to define some defaults for a host name. The manual says extension= and zend_extension= aren't allowed in [HOST=] and [PATH=] (see above). I figured out that you can easily fix that with adding [PHP] after your definitions.

For example hosts.ini:
display_errors = on


this will change the section back to [PHP] where extension= and zend_extension= is allowed.

Note that you cannot usefully set syslog.* in [PATH=] (and probably [HOST=]) sections, since the syslogger is initialized only once per php-fpm worker process, and not per request.

Just developed the probably first php.ini hack to add commands which will only be parsed before PHP 5.3 when using mod_php.


# Disable eAccelerator by default
eaccelerator.enable = 0

# Now, to prevent incompatibilities with Zend Optimizer+, we
# want to enable eAccelerator only in PHP 5.2 or lower.
eaccelerator.enable = 1


What is happening here? In PHP 5.3, php.ini sections to set up PHP on a per host basis have been introduced:


These sections only work in CGI/FastCGI mode, however there still seems to be a difference in how the php.ini file is parsed in PHP 5.2 and PHP 5.3 when using mod_php: PHP 5.3 ignores everything below the line [HOST=*], whereas PHP 5.2 does not.

In the above example, PHP 5.3 only reads "eaccelerator.enable = 0" and then stops at the invalid command [HOST=*]. However, PHP 5.2 seems to ignore the invalid command and parses the whole configuration file, ending up with "eaccelerator.enable = 1".

Adding PATH= applies only to the named path and does not include sub-directories, you have to add a PATH= value for each sub-directory.

Also some settings have no effect even though phpinfo recognises and displays the per-folder value as the 'local' value, and the default as the 'master' value.

'fastcgi.impersonate' always uses the master setting.

On Windows IIS 7 server I noticed that [PATH=] was not listened to. [HOST=] however worked.
