how to convert Array to object in PHP ?

$testdata=array("one"=>1,"two"=>2);

function MultiDimensionsArrayToObject($ar){
	$r=new stdclass();
	foreach($ar as $key=>$value){
		if(is_array($value)){
		$r->$key=MultiDimensionsArrayToObject($value);			
		}else {
		$r->$key=$value;			
		}

	}
	return $r;
}


$a=array("one"=>array("third"),"two");
 
$result=MultiDimensionsArrayToObject($a);
print_r($result);

stdClass Object ( [one] => stdClass Object ( [0] => third ) [0] => two )

function ArrayToObject($ar){
	$r=new stdclass();
	foreach($ar as $key=>$value){
		$r->$key=$value;
	}
	return $r;
}
$ar=array("data","is","more","important");
$r=ArrayToObject($ar);
print_r($r);

$obj = (object) array("one"=>1,"two"=>2);

$car=array("car"=>array("name"=>"tesla"));
 
$car_json=json_encode($car);
$car_obj=json_decode($car_json));
 print_r($car_obj);

stdClass Object ( [car] => stdClass Object ( [name] => tesla ) )
