Earlier this day I tried to add new php version.
I did it without stopping services, which prompted a few scary "entry point not found error". Just restarted and all worked.
But is there a reason why the quick php version switch doesn't restart services automatically ?
And whie we are at it, (I don't know if wamp allows it), I manage a few project over different PHP versions. Could we attribute a php version by domain, instead of having to manually switch ?
