An array stores multiple values in one single variable
An array is a special variable, which can hold more than one value at a time.
If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this:
However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300?
The solution is to create an array!
An array can hold many values under a single name, and you can access the values by referring to an index number.
In PHP, the array() function is used to create an array:
In PHP, there are three types of arrays:
The count() function is used to return the length (the number of elements) of
an array:
<?php
$cars = array("Volvo", "BMW", "Toyota");
echo count($cars);
?>
For a complete reference of all array functions, go to our complete PHP Array Reference.
The reference contains a brief description, and examples of use, for each function!
Use the correct function to output the number of items in an array.
$fruits = array("Apple", "Banana", "Orange");
echo ;
