基于密钥将多维数组拆分为两个阵列

Question

我对PHP World非常陌生，并且从最近三天就陷入了这个问题。

Array 
(
    [0] => stdClass Object 
     (
      [sim_id] => 15 
      [Tarrif_code] => D34 
      [rental] => USD 345 
      [service_provider] => Vodafone 
      [incoming_calls] => 3.2 /sec 
      [local_outgoing] => 3.2 /sec 
      [international_call] => 3.2 /sec 
      [company_name] => Airtel 
      [local_text] => 
      [international_text] => 
      [data] => 2G 
      [sim_type_id] => 1 
      [offer_short_descrption] => 
      [validity] => 
      [dialing_instruction] => 
      [recharge_instruction] => 
      [usage_warning] => 
      [country_id] => 1 
      [type] => Prepaid 
     ) 
) 

，其结果应该是

Array 
(
    [0] => stdClass Object 
     (
      [sim_id] => 15 
      [Tarrif_code] => D34 
      [company_name] => Airtel    
      [rental] => USD 345 
      [service_provider] => Vodafone 
      [country_id] => 1 
      [type] => Prepaid 


    [1] => stdClass Object 
     (
      [international_call] => 3.2 /sec 
      [incoming_calls] => 3.2 /sec 
      [local_outgoing] => 3.2 /sec) 
      [local_text] => 
      [international_text] => 
      [data] => 2G 
      [sim_type_id] => 1 
      [offer_short_descrption] => 
      [validity] => 
      [dialing_instruction] => 
      [recharge_instruction] => 
      [usage_warning] => 
     ) 
)

关于问题提供的数据：

$arr[0] = new stdClass; 

$arr[0]->id = 1; 
$arr[0]->name = 2; 
$arr[0]->state = 3; 
$arr[0]->land = 4; 

$arr2[0] = new stdClass; 

foreach($arr[0] as $k => $v) 
{ 
    if (!in_array($k, array('id', 'land')))// array of keys for first object 
    { 
     $arr2[0]->{$k} = $v; 
     unset($arr[0]->{$k}); 
    } 
} 

var_dump($arr[0]); 
echo "<br>"; 
var_dump($arr2[0]); 
exit;
