Chapter 6. PHP Arrays

In Chapter 3, I gave a very brief introduction to PHP’s arrays—just enough for a little taste of their power. In this chapter, I’ll show you many more things that you can do with arrays, some of which—if you have ever used a strongly typed language such as C—may surprise you with their elegance and simplicity.

Arrays are an example of what has made PHP so popular. Not only do they remove the tedium of writing code to deal with complicated data structures, but they also provide numerous ways to access data while remaining amazingly fast.
