二维数组 SimpleXMLElement Object 转换为普通二维数组

下面为输出的带SimpleXMLElement Object的二维数组，如何能把里面的SimpleXMLElement Object全部去掉变成普通二维数组。

Array ( [0] => SimpleXMLElement Object ( [FavType] => 2 [FreeSum] => 1500 [FreeCurrent] => 965 [FavCode1] => 1 [FavCode2] => 4 [FavOfferInfo] => 201407乐享4G 299元套餐 )
[1] => SimpleXMLElement Object ( [FavType] => 2 [FreeSum] => 500 [FreeCurrent] => 18 [FavCode1] => 1 [FavCode2] => 2 [FavOfferInfo] => 201407乐享4G 299元套餐 )
[2] => SimpleXMLElement Object ( [FavType] => 3 [FreeSum] => 30 [FreeCurrent] => 30 [FavCode1] => 4 [FavCode2] => 8 [FavOfferInfo] => 天翼-集团0元30M后向流量包 )
[3] => SimpleXMLElement Object ( [FavType] => 3 [FreeSum] => 30 [FreeCurrent] => 30 [FavCode1] => 4 [FavCode2] => 8 [FavOfferInfo] => 天翼客服赠送30M省内流量包 )
[4] => SimpleXMLElement Object ( [FavType] => 3 [FreeSum] => 4096 [FreeCurrent] => 1857.32 [FavCode1] => 4 [FavCode2] => 8 [FavOfferInfo] => 201407乐享4G 299元套餐 ) )

function ObjectToArray($o) {  if(is_object($o)) $o = get_object_vars($o);  if(is_array($o))     foreach($o as $k=>$v) $o[$k] = ObjectToArray($v);  return $o;}
