在.htaccess中检测对php_value / php_flag的支持以抑制错误 - PHP CGI模式 - mod_php

Question

I use php_value and php_flag rules in .htaccess such as:

php_value upload_max_filesize 100M

But this causes an error when the server is running in CGI mode instead of Apache mode, and instead I have to use php.ini rules such as:

upload_max_filesize = 100M

My code libraries needs to work for either mode, without manual changes for each server.

It took me a while to find a solution to allow both methods to be in place, and as it was hard to find I thought I'd post my solution here.

Answer 1

You can detect mod_php in .htaccess and ensure that these directives are only attempted when supported. In .htaccess:

<IfModule mod_php5.c>
   php_value upload_max_filesize 100M
   php_flag ...
</IfModule>

Note: Depending on your setup you might need to change mod_php5.c to mod_php4.c or mod_php.c .

In addition, you can manually stop the redundant php.ini file from being publicly accessible when in php mode using the following in .htaccess:

<Files ~ "\.ini">
   Order allow,deny
   Deny from all
</Files>

Hope this saves you some time!
