I've been requested to upgrade php on a number of systems. Currently, they are running version 4.3.4, and the most recent upgrade on the php.net site was version 5.1.6. I've never done this before, and have little clue what I'm supposed to be doing. I'm hoping that once I get it figured out for one system, I can upgrade the others with the same instructions without much trouble. (Hope-hope-hope)
First question: As far as I can tell, the systems in question are running the Apache2 webserver. Will I need to down Apache before I upgrade PHP, or should I leave it running?
More questions to come, no doubt.
Thanks in advance,
