Find an Object in an array by comparing Object->value to all Object->values in array PHP

So my array contains objects like this:

$arr = array(
    new Card('10', 'Spades'),
    new Card('Jack', 'Diamonds'),
    new Card('King', 'Spades')
);

Now I have a function:

function hasCard(Card $card) {
    if (in_array($card, $arr)) return true;

    return false;
}

Now above does not really work since I need to compare ($card->rank == $arr[$x]->rank) for each element in that $arr without looping. Is there a function on PHP that allows you to modify the compareTo method of array_search?

I'd suggest using array_filter here. (Note: make sure $arr is available inside the hasCard function)

function hasCard(Card $card) {
    $inArray = array_filter($arr, function($x) use($card){
        return $x->rank === $card->rank;
    });

    return count($inArray) > 0;
}

The $arr variable is not going to be available within the function hasCard, unless you pass it as a parameter.

To answer your question, look at array_filter. This will get you a callable function in which you can pass the $arr and $card as parameters.
