$unique = array();

foreach($objects as $object) {
    $unique[$object->owner_guid] = $object;
}

var_dump($unique);

@RIADev `$unique` will contain 1 object per `owner_guid`, you can get the unique `owner_guid` by `array_keys($unique)` – FuzzyTree Jul 23 '14 at 10:55
Hey that can be done so easily...but what my question by using owner_guid can i make the master array unique – UI Dev Jul 23 '14 at 10:56
