Practical PHP Programming:Array-specific functions

From IpbWiki

Although arrays are great by themselves, the best parts of their usefulness only come out when you use special array functions to manipulate your data – this was why we had to cover functions before arrays.

There are quite a few array functions all doing a variety of things, and you need not learn them all – your best bet is to give them all a try so that you at least know how they work, then get back to working on normal code. You'll soon learn what works for you best!
