Hoe filteren op array in een array?

Ik heb momenteel deze code:

	<?php
header('Content-Type: application/json');
	
$content =Â  '[{"DateGPS":"n\/a","DateReceived":"n\/a","Longitude":6.0418997,"Latitude":51.42666,"Speed":0,"DOP":"n\/a","DOP_status":"n\/a","VehicleNumber":[9585,9581],"VehicleType":"Onbekend","TrainNumber":3575,"Source":"OBIS","Status":"n\/a"},
{"DateGPS":"n\/a","DateReceived":"n\/a","Longitude":5.281358,"Latitude":52.208084,"Speed":0,"DOP":"n\/a","DOP_status":"n\/a","VehicleNumber":[2425],"VehicleType":"NS SLT vier-delig","TrainNumber":5578,"Source":"OBIS","Status":"n\/a"},
{"DateGPS":"n\/a","DateReceived":"n\/a","Longitude":5.2100635,"Latitude":52.13158,"Speed":102,"DOP":"n\/a","DOP_status":"n\/a","VehicleNumber":[4232],"VehicleType":"NS ICMm vier-delig","TrainNumber":11781,"Source":"OBIS","Status":"n\/a"},
{"DateGPS":"n\/a","DateReceived":"n\/a","Longitude":4.467521,"Latitude":51.924637,"Speed":8,"DOP":"n\/a","DOP_status":"n\/a","VehicleNumber":[9571],"VehicleType":"Onbekend","TrainNumber":2272,"Source":"OBIS","Status":"n\/a"},
{"DateGPS":"n\/a","DateReceived":"n\/a","Longitude":6.098261,"Latitude":52.50184,"Speed":0,"DOP":"n\/a","DOP_status":"n\/a","VehicleNumber":[1757,7334],"VehicleType":"NS E-LOC 1700","TrainNumber":5657,"Source":"OBIS","Status":"n\/a"}]';
$array = json_decode($content, true);
	$resulted_array = array_values(array_filter($array,function($v){ return ($v['TrainNumber'] == '2272');}));
        if (count($resulted_array) == 1) // Als hij niet 1 is is het item niet gevonden...
        $resulted_array = $resulted_array[0];
        echo json_encode($resulted_array);
	

Dit werkt perfect, en ik kan hiermee dus filteren op het element waarin TrainNumber gelijk is aan 2272.
Echter wil ik graag filteren op één van de nummers die in de array VehicleNumber[] voorkomt. Hoe kan ik dat doen?

Was gewoon een simpele in_array()
