In PHP, as in all programming languages, data types are used to classify one particular type of data. This is important because the specific data type you use will determine what values you can assign to it and what you can do to it (including what operations you can perform on it). In this tutorial, we will go over the important data types native to PHP. This is not an exhaustive investigation of data types, but will help you become familiar with what options you have available to you in PHP.
