PHP constant array
In PHP 5.6, constant arrays can only be defined through const, and in PHP 7, they can be defined through define().
Example
<?php
// 使用 define 函數(shù)來(lái)定義數(shù)組
define('sites', [
'Google',
'php',
'Taobao'
]);
print(sites[1]);
?>The execution output of the above program is:
php
