Actually, if you really want to learn PHP then CodeIgniter isn't the best place to start IMO. It's great to use as a tool for production. It's probably okay to get going at the very beginning. But if you want to really learn PHP, especially the new additions for PHP 5.3 then I suggest looking the code and using a PHP 5.3 framework. Look for a really small one so that you can see everything in the framework without having to look through a ton of files. Fatfree is one good example. A CodeIgniter based PHP 5.3 framework is fuelphp.
