Php “如何显示公司名称”；只有"；关于好友工作历史（facebook api）

我一直在获取我的facebook好友的工作记录。但结果是一个数组，其内容如下：

 {
 "id": "xxx", 
 "friends": {
"data": [
  {
    "name": "Indiarto Priadi",

      }, 
      {
        "employer": {

现在我想在我的页面上“只”显示雇主的名字，但我找不到这样做的方法。 这是我的密码：

$userFriends = $facebook->api('/'.$userId.'/friends');

for($i=0;$i<=3;$i++){ //retrieved friends (max 4 persons)
        $value=$userFriends["data"][$i];
        echo "<div id='$value[id]'>";
        $profile = $facebook->api("/".$value["id"]);
        $friendsWork = $facebook->api("/".$value["id"]."?fields=work");
        echo "<strong>".$profile["name"]."<br></strong>";
        echo " <img src='https://graph.facebook.com/".$value["id"]."/picture'><br>";
        echo "Username : ".$profile["username"]."<br>";
        echo "Local : ".$profile["locale"]."<br>";
        echo "Birthdate : ".$profile["birthday"]."<br>";

        print_r($friendsWork); // <--- the result is an array

        echo "<hr>";
        echo "</div>";
    }

$userFriends=$facebook->api（'/'.$userId./friends'）；
对于（$i=0；$iapi（“/”$value[“id”]）；
$friendsWork=$facebook->api（“/”$value[“id”]。“？fields=work”）；
echo“”$profile[“name”]。“
”；
回声“
”；
回显“用户名：”.$profile[“用户名”]。“
”；
echo“Local:”.$profile[“locale”]。“
”；
回音“生日：”.$profile[“生日”]。“
”；
print_r（$friendsWork）；//您只需解析获得的数组，如下所示-

$userFriends = $facebook->api('/'.$userId.'/friends?fields=work,name');

foreach($userFriends['data'] as $friend)
{
   $friend_name = $friend['name'];
   $emp_name=array();
   // list of all employers of this friend
   if(isset($friend['work']))
   {
       foreach($friend['work'] as $work)
       {
         array_push($emp_name, $work['employer']['name']);
       }
   } 
   else
   {
       $emp_name = "N.A.";
   }
}

给你，没什么特别的，我只是照我在评论中说的做了

$json = '{

}}}'; // remember the last two closing curlys, you left them out of the code block in the OP.

  $obj = json_decode($json);

  foreach ($obj->friends->data as $friend) {
    echo '<h1>' . $friend->name . '</h1>';
    foreach ($friend->work as $job) {
      echo 'Employee: ' . $job->employer->name . '<br/>';
    }
    echo '<hr>';
  }

从json解码到对象或数组，然后获取您想要的任何信息。您能给我代码吗？我尝试了json解码，但只返回了错误。ThanksI尝试回显$emp_名称并显示错误：“注意：未定义的索引：在第95行（第2个foreach）的PATH\index.php中工作警告：为foreach（）提供的参数无效”事实上，在95'行的PATH\index.php中，所有用户可能都没有facebook上的工作信息。我已经编辑了答案，请检查。仍然显示相同的错误。我仍然不明白为什么在第二次foreach时出现错误。您使用了确切的代码吗？您能告诉我确切的错误吗？我已经编辑了代码，请进一步检查
