I've been working with PHP for about 8 years now and if there's one thing i hate are the so called experts/gurus. It seems too common nowadays that when a article about PHP gets posted there are people in line ready to smash it. You guys take the fun out of writing code. @beberlei you could have kept that shhh to yourself. I'm sure @lornajane is all aware of SQL injections and honestly I'm glad she left it out this post was already long enough.
If you're new to OOP or even PHP I say have fun and enjoy building stuff. You can read a 100 books and 100 blog posts and there will always be someone smashing what's written, as if they invented the language.
@derickrethans I'm a big fan sorry I missed you @atlantaPHP
And @lornajane thanks for taking the time to contribute
