how can i check if an array value is available inside an array of stdclass object

I'm trying to check if the of an id is available inside this array of std objects, i do not want to loop through the array as it will not display the correct information. My code is as follows:

  Array(
    [0] => stdClass Object
        (
            [name] => My Name
            [id] => 1234567890
        )
    [1] => stdClass Object
        (
            [name] => Other User Name
            [id] => 987654321
        )
  )

I tried using in_array method and it doesnt find the id key and value.

Thank you D~~

With the help of Anzeo's answer I upgraded it a bit to work with other properties and to be used in conditional statements, take a peek:

function my_in_array($needle, $haystack = array(), $property){
    foreach ($haystack as $object) {
        if($object->$property == $needle){
            return true;
        } else {
            return false;
        }
    }
}
foreach($foo as $bar) {
    if(!my_in_array($bar, $arrWithObjects, 'id')) {
        //do something
    }
}

Hope this is useful for someone else

EDIT

I also found a nice trick to convert the object's properties into an array, that might help in some situations.

foreach($arrWithObjects as $obj) {
    $objProps = get_object_vars($obj);
    if(in_array('My Name', $objProps)) {
        //do something
    }
}

You'll need to loop the array to perform a check on an attribute of the objects inside the array. Write a function that will return your desired value like (pseudo-code):

function returnObjectForId($idToMatch){
    foreach ($array as $i => $object) {
        if($object->id == $idToMatch){
            return $object
        }
    }
}
