					<description>Well, thanks for this nice article but I think you should reconsider your tip about &quot;include_once/require_once&quot;.

First of all, what files are best included only once? files containing classes and/or functions. So you'd better check for their existence with class_exists()/function_exists() instead of including them blindly.

Second and most importantly, include_once/require_once are a lot slower than their counterparts (assuming you use an opcode cache). See http://talks.lerdorf.com/show/nz2/16 for a better explanation :)</description>
