1.2.222. Constant Case Preference

Define() creates constants which are case sensitive or not.

The analyzed code has less than 10% of one of them : for consistency reasons, it is recommended to make constant sensitivity definition consistent.

Note that define() used to allow the creation of case-sensitive constants, but this is deprecated since PHP 7.3 and will be removed in PHP 8.0.

<?php

    define('A1', 1);
    define('A2', 1);
    define('A3', 1);
    define('A4', 1);
    define('A5', 1);
    define('A6', 1);
    define('A7', 1);
    define('A8', 1);
    define('A9', 1);
    define('A10',1);

    define('A10',1, true);

?>
