在数组的多维数组中查找值

Question

以下函数将检索主要在大学中给定主题的活动用户的朋友列表。数据是从Facebook GRAPH API中提取的。 （此功能）...

function getCollegeFriends() { 
     $config = array(
     'appId' => 'XXXXXXXXXXXXX', 
     'secret' => 'XXXXXXXXXXXXXX', 
     ); 
     $facebook = new Facebook($config); 
     $user_id = $facebook->getUser(); 
     try { 
     $fql = "select uid,name,education from user WHERE uid IN (select uid2 from friend where uid1=($user_id))"; 
     $param = array(
     'method' => 'fql.query', 
     'query'  => $fql, 
     'callback' => '' 
     ); 
     $fqlResult = $facebook->api($param); 
     } 
     catch(Exception $o){ 
     d($o); 
     } 

     $friends = $fqlResult; 
     $friends_BA = array(); 
     foreach ($friends as $friend) { 
     $isBA = false; 
      if (is_array($friend['education'])) { 
       foreach ($friend['education'] as $school) { 
       if (isset($school)) { 
        foreach ($school['school'] as $name) { 
         $lowerName = strtolower($name); 
         if (strpos($lowerName, 'university of central florida') !== false || strpos($lowerName, 'ucf') !== false) { 
         $friends_BA[] = $friend['name']; 
         continue 3; // skip to the next friend 


         } 
        } 
        } 
       } 
      } 
      } 
      echo '<pre>'; 
      print_r($friends_BA); 
      echo '</pre>'; 
     } 

现在我工作的一个函数返回的谁在同一家公司工作的朋友列表，持有相同的工作岗位等。以下是我的失败刺伤功能：

function getWorkerFriends() { 
     $config = array(
     'appId' => 'XXXXXXXXX', 
     'secret' => 'XXXXXXXXX', 
     ); 
     $facebook = new Facebook($config); 
     $user_id = $facebook->getUser(); 
     try { 
     $fql = "select uid,name,work_history from user WHERE uid IN (select uid2 from friend where uid1=($user_id))"; 
     $param = array(
     'method' => 'fql.query', 
     'query'  => $fql, 
     'callback' => '' 
     ); 
     $fqlResult = $facebook->api($param); 
     } 
     catch(Exception $o){ 
     d($o); 
     } 

     $friends = $fqlResult; 
     $friends_BA = array(); 
     foreach ($friends as $friend) { 
     $isBA = false; 
      if (is_array($friend['work_history'])) { 
       foreach ($friend['work_history'] as $employer) { 
       if (isset($employer)) { 
        foreach ($employer['location'] as $name) { 
         $lowerName = strtolower($name['company_name']); 
         if (strpos($lowerName, 'ubs') !== false || strpos($lowerName, 'merion') !== false) { 
         $friends_BA[] = $friend['name']; 
         continue 3; // skip to the next friend 


         } 
        } 
        } 
       } 
      } 
      } 
      echo '<pre>'; 
      print_r($friends_BA); 
      echo '</pre>'; 
     } 

该解决方案只是返回一个空数组，但测试用户确实有满足函数要求的朋友。以下是用户朋友列表的数组。我们将不胜感激任何有关建议解决方案的帮助。我在第三天现在这个问题的：

（注：每个[OFFSET]是一个不同的朋友活跃用户：

的var_dump为每个变量，直到找到一个空，这样的如下 假设你的Facebook连接的东西是所有工作正常尝试下面的代码，这应该给你一些有用的输出。

function getWorkerFriends() { 
    $friends = $fqlResult; 

    echo "\$friends <br/>"; 
    var_dump($friends); 

    $friends_BA = array(); 
    foreach ($friends as $friend) { 
    $isBA = false; 

     echo "\$friend <br />"; 
     var_dump($friend); 


     if (is_array($friend['work_history'])) { 
      foreach ($friend['work_history'] as $employer) { 

       echo "\$employer <br />"; 
       var_dump($employer); 

      if (isset($employer)) { 
       foreach ($employer['location'] as $name) { 

        echo "\$name <br />"; 
        var_dump($name); 

        $lowerName = strtolower($name['company_name']); 
        if (strpos($lowerName, 'ubs') !== false || strpos($lowerName, 'merion') !== false) { 
        $friends_BA[] = $friend['name']; 

        echo "Continue to next friend! <br />"; 

        continue 3; // skip to the next friend 


        } 
       } 
       } 
      } 
     } 
     } 
     echo '<pre>'; 
     print_r($friends_BA); 
     echo '</pre>'; 
    }
