I came across plenty of other security stuff that’s a bit too advanced for me right now, like ways to validate the size of files uploaded through a form and that weird thing called “regular expressions”. So I have some light reading for tonight.

Your tutorials have been so incredibly helpful! I’ve been working with PHP and MySQL for awhile now, but I just started developing scripts and programs of my own. Your videos are friendly and to-the-point. But the best thing is that you’re learning as you go, and you face the problems other beginners (such as myself) are bound to encounter also.

Another great one! PHP security is one of the most important lessons. So many people write insecure code.
