One of the giveaways I’m planning to include on the CD-ROM that comes with the issue of PHP Magazine containing my article about the ZCE exam is a color-coded function reference sheet that comes in very handy when studying for the exam. I hadn’t seen this level of concision and focus on core functions available in either the PHP Pocket Reference or other freely available references. So I wrote my own, and used it to prepare for the ZCE.
Enjoy!
