好的,我有一个问题。我想设置一个新闻提要,这将显示用户在放置时收到的问题和评论。我设置了一个函数来完成所有这些。同样,我不知道它是否是最有效的,但我只想让它工作。所以这就是我所拥有的
public function foo ()
{
//Retrieve all of the questions
$Statement = $this->Database->prepare("SELECT * FROM table WHERE condition = ?");
$Statement->execute(array($this->variable));
while ($row = $Statement->fetch(PDO::FETCH_ASSOC))
{
$id[] = $row["id"];
$question[] = $row["question"];
$asker[] = $row["asker"];
$timestamp[] = $row["timestamp"];
$likes[] = $row["likes"];
}
$iLimit = count($id); //Set a limit based on the size of the array
if ($iLimit > 0)
{
//Save everything in an array for the questions
for ($iCount = 0; $iCount < $iLimit; $iCount++)
{
$question[$iCount] = Array ( "id" => $id[$iCount],
"text" => $question[$iCount],
"username" => $asker[$iCount],
"timestamp" => $timestamp[$iCount],
"likes" => $likes[$iCount] );
}
}
//Retrieve all of the comments
$Statement = $this->Database->prepare("SELECT * FROM table WHERE condition = ?");
$Statement->execute(array($this->variable));
while ($row = $Statement->fetch(PDO::FETCH_ASSOC))
{
$id[] = $row["id"];
$comment[] = $row["comment"];
$commenter[] = $row["commenter"];
$timestamp[] = $row["timestamp"];
$likes[] = $row["likes"];
}
$iLimit = count($id); //Set a limit based on the size of the array
if ($iLimit > 0)
{
//Save everything in an array for comments
for ($iCount = 0; $iCount < $iLimit; $iCount++)
{
$comment[$iCount] = Array ( "id" => $id[$iCount],
"text" => $comment[$iCount],
"username" => $commenter[$iCount],
"timestamp" => $timestamp[$iCount],
"likes" => $likes[$iCount] );
}
}
//Merge the two arrays
$aNewsFeed = array_merge($question, $comment);
foreach ($aNewsFeed as $row)
{
$aOrdered[] = $row["timestamp"];
}
array_multisort($aOrdered, SORT_DESC, $aNewsFeed); //Sort the array
return $aNewsFeed;
} //end getNewsFeed
然后我使用 foreach 循环调用它
foreach ($Class->foo() as $news)
{
echo $news["text"]
}
但每次它总是给出两个额外的 foreach 循环的空白运行。或者我不知道它是否实际上是数组的一部分,因为如果它是 foreach 循环的问题,通常它会发出错误。我认为它必须是 array_merge() 函数的问题,但我不完全确定。有任何想法吗?
感谢您的帮助。对此,我真的非常感激。
