I'm on the stage of learning OOP with the help of PHP and David Powers book (PHP Object Oriented Solutions). I'm on the chapter 3, where he talks about using DateTime class. I'll like to see the implementation of the DateTime class in order to underatnd how OOP realy works.
1) Where/how can I find the source code of DateTime class?
2) For a beginner is useful to see the code source of such classes, or is better to stay away from the messy things at this level?
分享 Don't bother trying to look at the code for the built-in PHP classes; they're not written in PHP (they're in C), so it won't teach you anything about writing PHP. The code is available if you want it, but is only going to be useful if you already know C)
However there are lots of good example classes available. The PEAR repository contains loads of PHP classes which can be good for learning. You might also want to download some of the examples in the appropriately named PHPClasses.org.
