Currently my server is running PHP 5.2.10. I want to upgrade to the latest version of PHP which is 5.3.2. The problem is that this site is not my site, it's someone else's site who some guy built and then disappeared so I'm kind of 'taking over' maintaining it so to speak.
I'm a very good web designer but I am no PHP/MySQL guru (not yet at least). I know enough to get me around but not as much as some of you guys.
Anyhow, the PHP code on the server now all works great with PHP 5.2.10 but I am worried if I upgrade it some things won't work. Is there any way to find out what might not work anymore if I upgrade? I just want to cover my bases so that things don't suddenly stop working if I upgrade.
Also, same thing with upgrading Apache. Currently the server is running Apache 2.0 but I want to upgrade to 2.2. Just want to make sure I won't have any problems with that as well.
Thanks guys! I really appreciate any help.
