1.2.899. Overwritten Class Constants¶

Those class constants are overwriting a parent class’s constant. This may lead to confusion, as the value of the constant may change depending on the way it is called.

<?php

class foo {
    const C = 1;
}

class bar extends foo {
    const C = 2;

    function x() {
        // depending on the access to C, value is different.
        print self::C.' '.static::C.' '.parent::C;
    }
}

?>
