PHP 5.4.10 finally has phpapache2_4.dll on board. But take care: if you are using Apachelounge's apache builds you'll probably be better off with their phpapache2_4.dll, because they build Apache with VC10 and the precompiled PHP from php.net still is VC9. The apache builds on this site are VC9, so you can use the shipped phpapache2_4.
