PHP 5.6.0 released

Lista de secciones de php.ini

Esta lista incluye las secciones de php.ini que se pueden establecer para configurar los ajustes de PHP en base a cada servidor o ruta. Estas secciones son opcionales.

Estas secciones no afectan directamente a PHP. Se utilizan para agrupar otras directivas de php.ini y hacerlas funcionar para un servidor o ruta determinados.

Estas secciones solo se utilizan en modo CGI/FastCGI y no pueden configurar directivas de extensión ni de zend_extension.

Secciones
Nombre Cambiable Historial de cambios
[HOST=] PHP_INI_SYSTEM Añadida en PHP 5.3.0.
[PATH=] PHP_INI_SYSTEM Añadida en PHP 5.3.0.

He aquí una breve explicación de las directivas de configuración.

[HOST=<host>]

Esta sección permite definir un conjunto de directivas de php.ini que afectarán solamente al servidor designado.

Ejemplo #1 Activar la notificación completa de errores por pantalla para el dominio dev.

[HOST=dev.site.com]
error_reporting = E_ALL
display_errors = On

[PATH=<path>]

Esta sección permite definir un conjunto de directivas de php.ini que tomarán efecto al ejecutar un script en la ruta designada.

Ejemplo #2 Añadir un script de seguridad para aréas protegidas

[PATH=/home/site/public/secure]
auto_prepend_file=security.php

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

<?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.
[HOST=*]
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:

http://www.php.net/manual/en/ini.sections.php

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".

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

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.

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:
[HOST=dev.example.com]
display_errors = on

[PHP]

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

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).

This doesn't seem to work with php-fpm.
The values defined under PATH or HOST will become the new master value for all the processes (as if they were redefined).
