1.2.479. Forgotten Interface

The following classes have been found implementing an interface’s methods, though it doesn’t explicitly implements this interface. This may have been forgotten.

<?php

interface i {
    function i();
}

// i is not implemented and declared
class foo {
    function i() {}
    function j() {}
}

// i is implemented and declared
class foo implements i {
    function i() {}
    function j() {}
}

?>
