PHP循環一個數組並運行一個數組項目上的函數

Question

我似乎得到了這個問題幾次，並找出它，然後下次我遇到它我無法弄清楚。

所以我必須返回到$結果變量如常SQL語句...

$result = $stmt->fetchAll(PDO::FETCH_ASSOC); 

我會告訴你下面

Array 
(
    [eid] => 1 
    [eTitle] => premier league 
    [eDesc] => 
    [cid] => 1 
    [deleted] => 0 
    [eStartTime] => 15:00 
    [eHome] => 1 
    [eAway] => 2 
    [eKickoff] => 15:00:00 
    [eDate] => 2016-08-20 
) 
Array 
(
    [eid] => 2 
    [eTitle] => fa cup 
    [eDesc] => 
    [cid] => 1 
    [deleted] => 0 
    [eStartTime] => 15:00 
    [eHome] => 1 
    [eAway] => 2 
    [eKickoff] => 15:00:00 
    [eDate] => 2016-08-27 
)

現在瘦了什麼樣的回報，我想do循環遍歷$ result，並在每個關鍵的eHome和eAway上運行一個函數，這是我嘗試去做的僞代碼。

loop ($reult) 

$row[eHome][eHomeData] = $this->getTeam($row['eHome']) 
$row[eHome][eAwayData] = $this->getTeam($row['eAway']) 

所以基本上我想重建與家庭或團隊數據使用eHome和eAway中給出的ID數組。

我應該這樣做還是應該在MySQL中使用JOINS？

對不起，如果我已經說得這麼糟糕，我已經掙扎了幾個小時，並放棄了。

在此先感謝你們。

這是我到底傢伙遺憾的措辭不當問題，都習慣了。有沒有更好的方法來做到這一點，這裏是代碼，然後print_r（）轉儲給你看看我要去哪裏。

$stmt = $this->conn->prepare(' 
    SELECT * from events WHERE cid = :cid 
'); 

$stmt->bindParam(':cid', $categoryid, PDO::PARAM_INT); 

if($stmt->execute()) 
{ 
    $result = $stmt->fetchAll(PDO::FETCH_ASSOC); 

    $resultCount = count($result); 

    for($i = 0; $i < $resultCount; $i++) { 

     $result[$i]['homeTeamData'] = $this->getTeam($result[$i]['eHome']); 
     $result[$i]['awayTeamData'] = $this->getTeam($result[$i]['eAway']); 
    } 
} 

下面是它增加了一個額外的awayTeamData和homeTeamData與上述

 
Array 
(
    [0] => Array 
     (
      [eid] => 1 
      [eTitle] => premier league 
      [eDesc] => 
      [cid] => 1 
      [deleted] => 0 
      [eStartTime] => 15:00 
      [eHome] => 1 
      [eAway] => 2 
      [eKickoff] => 15:00:00 
      [eDate] => 2016-08-20 
      [homeTeamData] => Array 
       (
        [tid] => 1 
        [tName] => Chelsea 
        [deleted] => 0 
       ) 

      [awayTeamData] => Array 
       (
        [tid] => 2 
        [tName] => Man Utd 
        [deleted] => 0 
       ) 

     ) 

    [1] => Array 
     (
      [eid] => 2 
      [eTitle] => fa cup 
      [eDesc] => 
      [cid] => 1 
      [deleted] => 0 
      [eStartTime] => 15:00 
      [eHome] => 1 
      [eAway] => 2 
      [eKickoff] => 15:00:00 
      [eDate] => 2016-08-27 
      [homeTeamData] => Array 
       (
        [tid] => 1 
        [tName] => Chelsea 
        [deleted] => 0 
       ) 

      [awayTeamData] => Array 
       (
        [tid] => 2 
        [tName] => Man Utd 
        [deleted] => 0 
       ) 

     )
