Enabiling extension PHP.ini on Scriptcase - Ubuntu 13.10.

Hi, my sistem runs on Ubuntu 13.10 and works well. I worked on mysql but now i need to test other databases (my license is enterpise). When i try to use generic odbc the message is “odbc php must to be enabled”. Can someone tell me how doing this on Scriptcase - Apache/Conf/php.ini? The directory /opt/NetMake/v71/components/apache/Ext is empty (why?).
Thank you in advance.
