PHP - 配列を扱う

Question

私は以下のような配列を持っていると仮定します。どうすれば "vid = 2であるかどうかを確認してから、/ echo tidを得る"ことができますか？

Array 
(
    [29] => stdClass Object 
     (
      [tid] => 29 
      [vid] => 2 
      [name] => notebook 
      [description] => 
      [weight] => 0 
      [language] => 
      [trid] => 0 
     ) 

    [97] => stdClass Object 
     (
      [tid] => 97 
      [vid] => 1 
      [name] => DELL 
      [description] => 
      [weight] => 0 
      [language] => 
      [trid] => 0 
     ) 

) 

Answer 1

foreach($vids as $vid){ 
    if($vid->vid == 2){ 
     echo $vid->tid; 
    } 
} 

Answer 2

それは次のようになります。

foreach($tid as $key => $value){ 
    if($value->vid == 2){ 
     echo $value->tid; 
    } 
    }
