zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so
The zend and ioncube lines are added because a custom php.ini will disable those for your account if they are not contained within it. You can also just copy over /usr/local/lib/php.ini and make any changes that you want.
