php - JSON PHP ForEach

Question

JSON 提要：

    {
        "Group": [
          {
             "name": "HolderOne",
            "operators": [
            {
                "username": "ken",
                "status": 3
            },
     .....etc.....

代码：

 <?php 
 $json = file_get_content('path to feed');
 $data=json_decode($json); 

 echo $data->cGroup[0]->operators[0]->username; //WORKS!

 if (is_array($data->Group->operators))
  { foreach($data->Group->operators as $operator) 
     {if($operator->username == "ken") {echo $operator->status;}} 
  } else { echo 'NOT AN ARRAY'; } //DOESNT WORK - DISPLAYS NOT AN ARRAY
 ?>

我想说如果用户名是 Ken（或者我在编写更多代码时指定的任何内容）显示相应的状态。

所以...

  echo $data->Group[0]->operators[0]->username; //WORKS!

但...

    foreach($data->Group->operators as $operator) {if($operator->username == "ken") {echo $operator->status;}} 

...不 - 可能很明显，但任何人都可以看到我的问题吗？

干杯安迪

Answer 1

它必须是$data->Group[0]->operators, 或者循环Groups并在里面有另一个循环......

foreach($data->Group as $group){
    foreach($group->operators as $operator){
        if($operator->username == "ken") {echo $operator->status;}
    }
}

Answer 2

我认为这是真的：

foreach($data["Group"]["operators"] as $operators)
{
     if($operators["username"] == "ken")
     {
          echo $operators["status"];
     }
     else
     {
          echo 'NOT AN ARRAY';
     }
}
