1.2.232. Constant Used Below

Mark class constants that are used in children classes.

This analysis marks constants at their definition, not the current class, nor the (grand-)`parent <https://www.php.net/manual/en/language.oop5.paamayim-nekudotayim.php>`_.

<?php

class foo {
    // This constant is used in children
    protected PROTECTEDPROPERTY = 1;

    // This constant is not used in children
    protected LOCALPROTECTEDPROPERTY = 1;

    private function foobar() {
        // PROTECTEDPROPERTY is used here, but defined in parent
        echo self::LOCALPROTECTEDPROPERTY;
    }
}

class foofoo extends foo {
    private function bar() {
        // protectedProperty is used here, but defined in parent
        print self::PROTECTEDPROPERTY;
    }
}

?>
