Ok, I got it to work. It looks like Apache can't find the icu*.dll files (in the php directory).
So, one solution is to add "C:\wamp\bin\php\php5.3.9" (or similar directory) to your system PATH.
The other solution is to copy the icu*.dll files to your apache's bin directory.
A third option is to copy the icu*.dll files to your Windows system directory (system32 or SysWOW64).
