Per-directory configuration

[djn]

Some time ago I noticed something strange running a phpinfo() on what was then CPanel17 (I believe it was a register_globals unexpectedly set to On while the default was Off) and Andrew made me aware that using a php.ini in a website folder does change more stuff than what's in the php.ini only.

Today I found the time to test this and take some notes: I've run a phpinfo() on CPanel59 with a minimal php.ini (containing only register_globals = Off) and without it and run a diff on the resulting HTML. Might be useful to know that with even such a minimal config file:

• PHP declares the loaded php.ini to be the local one
• the ionCube PHP Loader, the Zend Extension Manager and the Zend Optimizer are not loaded
• allow_url_include turns to Off
• error_log changes from error_log to no value
• error_reporting changes from 6135 to no value
• expose_php turns to On
• extension_dir changes from /usr/local/lib/php/extensions/no-debug-non-zts-20060613 to /usr/lib/php/extensions/no-debug-non-zts-20060613
• include_path changes from .:/usr/lib/php:/usr/local/lib/php to .:/usr/lib/php
• max_input_time goes from 60 to -1 (oops!)
• memory_limit goes from 32M to 128M
• output_buffering goes from no value to 0
• precision goes from 12 to 14
• safe_mode_exec_dir goes from no value to /usr/local/php/bin
• sendmail_path doesn't really change, but has an added space at the end (?)
• the ffmpeg-php extension is not loaded
• mysql.allow_persistent turns to On
• PDO, pdo_mysql and pdo_sqlite extensions are not loaded
• registered save handlers go from files user sqlite to files user
• session.save_path goes from /tmp to no value
• the SQLite extension is not loaded
• url_rewriter.tags changes from a=href,area=href,frame=src,input=src,form=,fieldse t= to a=href,area=href,frame=src,form=,fieldset=

Anybody playing with the per-directory configuration of PHP might want to keep an eye on these values in case something behaves strange.

Not sure if it's an effect of the upgrade to PHP 5.2.12, but suddenly the settings in a php.ini started to apply to subfolders too.

is it possible to have different php.ini for every directory/subdomain?
I need to set different include_path for every subdomain.

I use it to running some demo/test/mockup sites to show to my clients. it is more simple than create cpanel account for every demo/test/mockup sites.

No, but you can use .htaccess to set PHP settings per directory. Refer to the recent posts in the annoucements forum.

It's the effect of the recent passage from Apache to LiteSpeed. Now a php.ini in the root folder applies to all subfolders, and php_value|php_flag commands in .htaccess are supported.

thank you for the help..
problem solved.. I use php.ini for main include in www directory, and use .htaccess for specific include in subdomain directory..

What's new with LiteSpeed

Been playing a little with this thing, just being curious. What I found is that you can have conflicting instructions in your php.ini (root folder only, no effect elsewhere) and your .htaccess (think php_flag|php_value), and the winner is .htaccess. Instructions there trump over php.ini.

Also, now we can do HTTP Authentication - as shown here. Nice.
