In Robert Peak's latest entry on his weblog today, he offers up a freely downloadable PHP reference sheet in PDF form.

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!

It's a nice little sheet, and the color-coding (red for integer, green for arrays, pink for booleans, etc) on both the function arguments and what they return make this one handy sheet to have around...
