  • ... and the long answer depends on why do you need this. If it'd be sufficient to check arguments in runtime, deceze's answer is right for you. But if what you need is IDE assistance, I suggest checking [this thread](http://stackoverflow.com/questions/778564/phpdoc-type-hinting-for-array-of-objects) for plenty of helpful hints. ) – raina77ow Aug 15 '12 at 12:39

No.

You'll need to manually check:

function foo(array $arr) {
    if (array_filter($arr, function ($i) { return !($i instanceof CCC); })) {
        throw new InvalidArgumentException('Array must contain instances of CCC');
    }

    ...
}
