錯誤的網關502等待~2min後頁面加載錯誤

Question

嗨， 我嘗試做一個小的形式爲學校和一切工作正常，因爲我做了「reorganizeVector（）」函數。現在，當我想在瀏覽器上嘗試我的表單（僅此網頁）時，它會加載2〜3分鐘，並且出現Bad Gateway 502錯誤。我幾乎可以肯定我的問題是在「reorganizeVector（）」函數中。我試圖找到我的功能有什麼問題，但我找不到我做錯了什麼。

，因爲它在這裏上午03點18，我會添加一些其他的文件，如「的index.php」明天，我必須早上5點的學校，所以醒來......

這將是感激，如果你能幫助我。
請幫幫我！

B.T.W.對不起我的英語不好，我是加拿大法語，我盡力做到最好。

我覺得你在這條線的無限循環進入：while(!empty($index));這好像是while循環沒有很好的界定。
