What is an array?

Arrays are special variables that can hold more than one value at the same time.

If you have a list of items (such as a list of car brands), storing these brand names in a single variable looks like this:

$cars1= "porsche"; $cars2= "BMW"; $cars3= "Volvo"

But what if you want to traverse the variable and find a specific value? Or what if you need to store 300 car brands instead of 3?

The solution is to create an array!

Arrays can store many values in a single variable name, and you can access a value by referencing an index number.
