1.2.1330. Use Lower Case For Parent, Static And Self

The special parent, static and self keywords needed to be lowercase to be usable. This was fixed in PHP 5.5; otherwise, they would yield a ‘PHP Fatal error: Class ‘PARENT’ not found’.

parent, static and self are traditionally written in lowercase only. Mixed case and Upper case are both valid, though. Until PHP 5.5, non-lowercase version of those keywords are generating a bug.

<?php

class foo {
    const aConstante = 233;

    function method() {
        // Wrong case, error with PHP 5.4.* and older
        echo SELF::aConstante;

        // Always right.
        echo self::aConstante;
    }
}

?>
