What is an Array?

An array is a special variable that can hold many values under a single name, and you can access the values by referring to an index number or name.


PHP Array Types

In PHP, there are three types of arrays:


Working With Arrays

In this tutorial you will learn how to work with arrays, including:


Array Items

Array items can be of any data type.

The most common are strings and numbers (int, float), but array items can also be objects, functions or even arrays.

You can have different data types in the same array.

Example

Array items of four different data types:

$myArr = array("Volvo", 15, ["apples", "bananas"], myFunction);

Array Functions

The real strength of PHP arrays are the built-in array functions, like the count() function for counting array items:

Example

How many items are in the $cars array:

$cars = array("Volvo", "BMW", "Toyota");
echo count($cars);
