面對數組的瓶頸

Question

我有下面的代碼顯示正確的結果對我來說，但不幸的是我不能將這些結果傳遞到我的HTML頁面並返回一定的值。

這是我的SQL語句：

$stmt = "SELECT * FROM "._CONST_TBL_EVENT_COMMENT." WHERE event_id = $record"; 

if($rs = $db->Execute($stmt)) 
{ 
    while($rsa = $rs->FetchRow()) 
    { 

     array_push($arrResult, array(
      "id" => $record, 
      "name" => $alumni->getAlumniNameForEventComment($rsa['member_id']), 
      "file_path" => $alumni->getAlumniImageForEventComment($rsa['member_id']), 
      "content" => $rsa['text'], 
      "date" => $rsa['modified_timestamp'] 
     )); 
    } 
} 

這是結果我得到：

Array ([0] => 
     Array ([id] => 1 [name] => 
      Array ([0] => Array ([name] => alisdfsadf)) 
      [file_path] =>Array ([0]=> Array ([file_path] => hydrangeas_23197.jpg)) 
      [content] => test test test test 
      [date] => 2014-05-08 00:00:00) 
     [1] => 
     Array ([id] => 1 [name] => 
      Array ([0] => Array ([name] => billy)) 
      [file_path] => Array ([0] => Array ([file_path] =>)) 
      [content] => sdfasdfas test 
      [date] => 2014-05-22 00:00:00) 
) 

但我想這樣我的結果顯示：

Array ([0] => Array([id] => 1 [name] => alisdfsadf 
[file_path] => hydrangeas_23197.jpg 
[content] => test test test test 
[date] => 2014-05-08 00:00:00) 

如何我做這個？我希望有人能幫助我。先謝謝了。

您在$ alumni類中的函數看起來是返回數組。 此基礎上，你已經給了，並試圖扭轉工程師輸出...

while($rsa = $rs->FetchRow()) 
{ 
    $allNamesArray = $alumni->getAlumniNameForEventComment($rsa['member_id']); 
    $firstNameArray = $allNamesArray[0]; 
    $name = $firstNameArray['name']; 

    // similar for file path. 

    array_push($arrResult, array(
     "id" => $record, 
     "name" => $name, 
     "file_path" => $alumni->getAlumniImageForEventComment($rsa['member_id']), 
     "content" => $rsa['text'], 
     "date" => $rsa['modified_timestamp'] 
    )); 
}

由於getAlumniXXXForEventComment函數返回數組，你要索引他們得到你想要的字符串。

if($rs = $db->Execute($stmt)) 
{ 
    while($rsa = $rs->FetchRow()) 
    { 
     $nameArray = $alumni->getAlumniNameForEventComment($rsa['member_id']); 
     $name = is_array($nameArray) ? $nameArray[0]['name'] : $nameArray; 
     $fileArray = $alumni->getAlumniImageForEventComment($rsa['member_id']); 
     $file = is_array($fileArray) ? $fileArray[0]['file_path'] : $fileArray; 
     array_push($arrResult, array(
      "id" => $record, 
      "name" => $name, 
      "file_path" => $file, 
      "content" => $rsa['text'], 
      "date" => $rsa['modified_timestamp'] 
     )); 
    }
