I’ll admit, one of the best things I love about PHP is that I don’t have to deal with all sorts of different ways to deal with data. At the base of the language we have nice primitives like strings, integers, floats, and Booleans, and we also have one of the most flexible structures known to programmers—the PHP Array. The array itself wears many hats. If you are coming from other languages, you have to think about the structure of ordered data in a few different ways. The reason for this tends to deal mostly with how we need to represent data and how we manipulate data. Different data has different requirements.
