questions about upgrading php
i want to upgrade my php version from 4.3.10 to 4.3.11.my server is a windows xp box running apache 2.0.54, mysql 4.1, and perl 5.8.6.
do i have to delete the whole php directory and reconfigure the server or can i just replace a few files. also, if i can just replace a few files, which files do i need to replace?
