PHP 7 – Constant Arrays

PHP 7 – Constant Arrays

In PHP 7, a new feature, spaceship operator has been introduced. Array constants can now be defined using the define() function. In PHP 5.6, they could only be defined using const keyword.
 

<?php
//define a array using define function
define('animals', [
  'dog',
  'cat',
  'bird'
]);
print(animals[1]);
?>

 

It produces the following browser output -

 

cat
