JSON PHP的ForEach

Question

JSON提要：

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

CODE：

<?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 
?> 

我想說的用戶名是否肯（或者我指定我的代碼更）顯示把對應的狀態。

所以......

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

但是......

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

......不 - 可能是一些顯而易見的，但任何人都可以看到我的問題嗎？

Answer 1

它必須是$data->Group[0]->operators，或遍歷Groups，並有內另一個循環...

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

Answer 2

我覺得這是真的：

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