搜索数组值和返回在PHP中的行

Question

找不到正确的答案，所以希望有人可以提供帮助。基本上要搜索[VIN]值，如果匹配，则返回[MEDIAID]或行。

 
Array 
(
    [0] => Array 
     (
      [CLIENTID] => GALLEY 
      [VIN] => WBAFDEG2317MCB73388 
      [MEDIAID] => 10011020061817-galley_082114-SDvcl-140880481613056500 
      [DEALERNAME] => Demo 
      [PUBLISHON] => 2014-08-28 
     ) 
    [1] => Array 
     (
      [CLIENTID] => GALLEY 
      [VIN] => WAULC68E74A053WE251 
      [MEDIAID] => 10011020061817-galley_082114-SDvcl-140880482109709900 
      [DEALERNAME] => Demo 
      [PUBLISHON] => 2014-08-26 
     ) 
    [2] => Array 
     (
      [CLIENTID] => GALLEY 
      [VIN] => WAULC68E74A053WE251 
      [MEDIAID] => 10011020061817-galley_082114-SDvcl-140880482109709900 
      [PUBLISHON] => 2014-08-26 
     ) 
)  

我需要在php中做到这一点。

功能结构从这个already answered question复制，我只是做了一些改动，使之成为您的应用程序工作：

function searchForId($id, $array) { 
    foreach ($array as $key => $val) { 
     if ($val['VIN'] === $id) { 
      return $val['MEDIAID']; 
     } 
    } 
    return null; 
} 

$array = array(
    0=> array(
    'CLIENTID' => 'GALLEY', 
    'VIN' => 'WBAFDEG2317MCB73388', 
    'MEDIAID' => '10011020061817-galley_082114-SDvcl-140880481613056500', 
    'DEALERNAME' => 'Demo', 
    'PUBLISHON' => '2014-08-28' 
    ), 
    1=> array(
    'CLIENTID' => 'GALLEY', 
    'VIN' => 'WAULC68E74A053WE251', 
    'MEDIAID' => '10011020061817-galley_082114-SDvcl-140880482109709900', 
    'DEALERNAME' => 'Demo', 
    'PUBLISHON' => '2014-08-26' 
    ), 
    2=> array(
    'CLIENTID' => 'GALLEY', 
    'VIN' => 'WAULC68E74A053WE251', 
    'MEDIAID' => '10011020061817-galley_082114-SDvcl-140880482109709900', 
    'DEALERNAME' => 'Demo', 
    'PUBLISHON' => '2014-08-26' 
    ),  
); 

$search = searchForId('WAULC68E74A053WE251', $array); 

var_dump($search); 

结果：

string(53) "10011020061817-galley_082114-SDvcl-140880482109709900"
