1.2.26. Already Parents Trait

Trait is already used a parent’s class or trait. There is no use to include it a second time, so one of them can be removed.

<?php

trait ta {
    use tb;
}

trait t1 {
    use ta;
    use tb; // also used by ta
}

class b {
    use t1; // also required by class c
    use ta; // also required by trait t1
}

class c extends b {
    use t1;
}

?>
