    Beispiel #1 class_uses() example

    <?php

    trait foo { }
    class     bar {
    use     foo;
    }

    print_r(class_uses(new bar));

    print_r(class_uses('bar'));

    spl_autoload_register();

    // use autoloading to load the 'not_loaded' class
    print_r(class_uses('not_loaded', true));

    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    Array ( [foo] => foo ) Array ( [foo] => foo ) Array ( [trait_of_not_loaded] => trait_of_not_loaded )
