=====PHP=====

The advice is to just use whatever your server comes preinstalled with. Of course, in real life things are never that simple.

==== Backports ====

If you're stuck on old version of Ubuntu (e.g. hosted webserver), you can try backports to upgrade your php version. Here's a backport of php 5.3.2 (required for Moodle 2.1) I found for Ubuntu Hardy (8.04):

https://launchpad.net/~sushkov/+archive/hardy-experimental/

Just follow the guide on launchpad.net and install the package with ''apt-get install php5''.

By the way, if you're installing php for Moodle, be sure that all related packages which are required by Moodle are there:

  * libapache2-mod-php5 		
  * php5 		    
  * php5-cgi 		
  * php5-cli 		
  * php5-common 
  * php5-curl 	
  * php5-gd 		
  * php5-mysql 	
  * php5-xmlrpc

If you need to hunt for backports use Google (duh): ''site:launchpad.net hardy OR "8.04" "libapache2-mod-php5" "5.3.2"''
