Search an Array with nested arrays and return

Question

The Array format

Array
(
[76ea881ebe188f1a7e7451a9d7f17ada] => Array
    (
        [rowid] => 76ea881ebe188f1a7e7451a9d7f17ada
        [id] => 1
        [qty] => 2
        [price] => 20
        [name] => First
        [options] => Array
            (
                [permName] => beer
            )

        [subtotal] => 40
    )

[e7a36fadf2410205f0768da1b61156d9] => Array
    (
        [rowid] => e7a36fadf2410205f0768da1b61156d9
        [id] => 3
        [qty] => 6
        [price] => 20
        [name] => Second
        [options] => Array
            (
                [permName] => achieve
            )

        [subtotal] => 120
    )

Is there a way for me to search this array for the title or in this case lets say e7a36fadf2410205f0768da1b61156d9 and once it is found just return the price and the qty values?

Any help would be greatly appreciated.

You can you array_key_exists function to check if there is any element with a given key.

$title = 'e7a36fadf2410205f0768da1b61156d9';   
if (array_key_exists($title, $arr)) {
    return array('price'=>$arr[$title]['price'], 'qty'=>$arr[$title]['qty']);
}

$title = 'e7a36fadf2410205f0768da1b61156d9';

if (isset($arr[$title])) {
    return array('price'=>$arr[$title]['price'], 'qty'=>$arr[$title]['qty']);
}

This function is enough.

function search_title($title, $array){
    if(array_key_exists($array[$title])){
        return array($array[$title]['price'],$array[$title]['qty']);
    }else{
        return array( false, false);
    }
}

Usage,

list ($price, $qty) = search_title('e7a36fadf2410205f0768da1b61156d9', $array);

if($price!==false){
    // search was successful
}
