PHP - 处理数组

Question

假设我有一个如下数组，我如何“检查vid = 2，然后获取/ echo tid”？

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

它应该是：

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