Declaring Arrays as Constants

You learned how to declare an array earlier.
Arrays can also be declared as constants.
Assigning a different value does not change the value.

How to declare an array in a constant

 define( 'constant name' , ['array value1' , 'array value2' , 'array value3']);  

The way you print an array is not too different.

Constant Array Output Method

 echo constant name[index];

So let's look at an example.

<?php
    define('DISNEY',['MICKEY', 'MINNIE', 'DUFFY']);
    echo DISNEY[0];
    echo '<br>';
    echo DISNEY[1];
    echo '<br>';
    echo DISNEY[2];
?>

Here is the resulting image
