Arrays allow us to assign multiple values into an array and store that into a variable.
First, we need to create a variable, and then we will store three items inside of an
array, and we do this inside of
$cars = array('BMW', 'Audi', 'Mercedes');
The different items inside the array have to be separated by a
If we try to echo out an array, it will give us an error because we can not echo out an array, but we can only echo out a specific index of our array.
Let's echo out the index of 1:
$cars = array('BMW', 'Audi', 'Mercedes'); echo $cars;
This will print out

So let's print out the first item (BMW) in our array:
array('BMW', 'Audi', 'Mercedes'); echo $cars; $cars =
It's crucial that you remember:
Arrays start off at
If you really do need to print out your array, you can use a function called
print_r. This will print in a readable format your array.
$cars = array('BMW', 'Audi', 'Mercedes'); print_r($cars);
