Does domain php ini override master?

[joximu]

As long as you use fastcgi and not mod_php:
There is only one php.ini for each customer (subdomains and aliases use the same php.ini): /var/www/fcgi/<customer>/php<4 or 5>/php.ini

I use PHP4 as default. But this depends on your configuration.

When you change something in a php.ini, maybe you need to reload apache - or wait some time until all running processes of this customer have have been finished...
