php.ini

Generally, you shouldn't need to change your php.ini, but if you do, this page is to share tips & tricks about Tiki-related configs.

You have to place your custom php.ini file in your Tiki root folder.
Keep in mind that some servers have two different php.ini files, one for php scripts used through a web server and browser, and another one for php scripts being run in the commadn line (CLI). These 2 are common locations for those 2 php.ini files (in Debian GNU/Linux servers):

/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini
