這是我的每個.php頁面。我可以讓它註冊並進入我的本地服務器。但是，當我進入登錄頁面並實際登錄時，它不會重定向到成員頁面。我不確定它是什麼問題。我對PHP很新，代碼看起來不錯。很簡單，但我試圖讓這個工作。任何幫助表示讚賞。謝謝。PHP標頭不能在本地服務器上工作

你得到的錯誤是什麼？ – 2015-02-24 03:50:30
在每個標題後添加'exit;'。另外，在打開PHP標記 （例如'<？php error_reporting（E_ALL）;）後立即將錯誤報告添加到文件頂部。 ini_set（'display_errors'，1）;'然後你的代碼的其餘部分，看看它是否產生任何東西。 還要把'或者死（mysqli_error（$ con））'添加到'mysqli_query（）'中。也刪除'@'符號;這是一個錯誤抑制器。 – 2015-02-24 03:52:07
注意：您應該在標題中使用位置，而不是位置。 – 2015-02-24 03:59:12
