Upgrading php4 on apache2

I currently have php 4.3.7 on my machine as an apache module (php4apache2.dll). I wanted to update php to 4.3.8 as recommended by the php.net site because 4.3.7 has many security issues. How do I upgrade it, just unzip and over-write everything in the c:php directory; and change the php.ini file to the new one? I couldn't find any info on how to upgrade php4 on apache2 as a module, which is kinda funny because it seems that was all I saw when I was first trying to install wamp a few weeks ago ((Shrug)).

Also, I briefly read a vague snippet somewhere on php as a dso module on apache, and that it was recommended over php as a standard module for upgrading php easier or something like that. Is this true?

I noticed that above, it says Thread is resolved. I didn't know I could change that myself, but I accidently did. However, the thread isn't resolved, I didn't find the answer anywhere yet.

Oh, I see. Makes perfect sense, I have to be logged in to change the resolved/unresolved status. Also consider this a bump. I'm sure someone has upgraded to a newer version before? Do I just replace the old php stuff with the new one to upgrade?

This is the process I followed in order to upgrade:

-Shutdown Apache
-Backup then delete the php4apache2.dll, php4ts.dll(???), and the php.ini files.
-Backup then delete the c:php directory
-unzip 4.3.8 to c:php and install as normal (I reused the php.ini file from 4.3.7).
-copy anything from your old php directory such as includes or modules into the current
-restart the webserver.

Basically you just manually uninstall php and then reinstall the new version. I'm sure there are easier ways, but I like to make sure I have a vanilla install. As always YMMV.
