Okay, I'm on CentOS 5.3 and I'm running an nginx/php/mysql server stack with FastCGI. One of my Twitter apps requires PHP to connect to the Twitter API, which uses OAuth. So I installed the OAuth module with PECL and confirmed that oauth.so was compiled in /usr/lib/php/modules and extension=oauth.so was added in PHP.ini. However, when I try to access the PHP file I get a fatal error, the OAuth class is not found. So I checked phpinfo() and the PHP.ini file hasn't been reloaded apparently.
So, how do I force PHP with FastCGI to update its configuration without restarting the server?
