By restarting apache you also reload mod_php, so if you have upgraded
your PHP between your last apache restart and this one that might be it.
and IIRC by restarting apache you also reload php.ini.

Another thing is that php5-pcre is now part of php5, and not an extra
extension. I don't know whether that is also for 5.1.

The function below seems working on 5.2.8 and 5.3.0-beta1.
