面对数组的瓶颈

Question

我有下面的代码显示正确的结果对我来说，但不幸的是我不能将这些结果传递到我的HTML页面并返回一定的值。

这是我的SQL语句：

$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'] 
     )); 
    } 
} 

这是结果我得到：

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) 
) 

但我想这样我的结果显示：

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

如何我做这个？我希望有人能帮助我。先谢谢了。

您在$ alumni类中的函数看起来是返回数组。 此基础上，你已经给了，并试图扭转工程师输出...

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'] 
    )); 
}

由于getAlumniXXXForEventComment函数返回数组，你要索引他们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'] 
     )); 
    }
