I've been searching for a while now on how to properly do this with no success.
Unfortunately due to corporate policy, I'm stuck managing Apache and PHP on a Windows server. When I originally set this up, I installed Apache from http://www.apachelounge.com/ and used the official PHP.net installer binary for 5.3.8 to automatically install PHP as a module for apache. Then when updated 5.3 builds came out, I simply downloaded and ran the installer and it properly upgraded PHP to the next minor revision (eg. 5.3.8 to 5.3.10). Now I see that there is no binary for PHP 5.4, just a .ZIP. I'm unsure on how to properly upgrade the server now and can't find any documentation.
Can anyone point me the right direction here?
