php.ini 配置段列表

这个列表包含 php.ini section,可以根据每个主机或路径进行设置以配置 PHP 环境。这些 section 是可选的。

这些 section 并不直接影响 PHP。它们用于将其他 php.ini 指令分组,并使其在特定主机或路径上生效。

这些 section 仅在 CGI/FastCGI 模式下使用,不能设置 extensionzend_extension 指令。

配置段
名字 可修改范围 更新日志
[HOST=] INI_SYSTEM  
[PATH=] INI_SYSTEM  

这是配置指令的简短说明。

[HOST=<host>]

该 section 允许定义一组在指定主机上生效的 php.ini 指令。

示例 #1 dev. 域名激活完整的屏幕错误报告

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

[PATH=<path>]

该 section 允许定义一组脚本从指定路径运行时生效的 php.ini 指令。

示例 #2 受保护的区域添加安全脚本

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

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 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.

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.

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

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.

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.
