 Profile you code before you start optimizing it! Otherwise it would be like travelling around a foreign city with signs written in an unreadable language witout any map or GPS. You’ll probably get somewhere, but you wouldn’t have any idea where you are, where you should go and how far are you from the place you need to be. Profiling would allow you to know which parts of code are worth investing into and which aren’t. You can use [[http://www.zend.com/en/products/studio/|Zend Studio/Debugger]] or [[/informatique/php/XDebug|Xdebug]] for that.
