登錄功能不能在PHP

嗨我有點麻煩檢查此代碼。它似乎在我本地的wamp服務器上工作得很好，但是當我在godaddy託管的服務器上運行時，它不起作用。我嘗試使用另一個託管公司的另一臺服務器，並將其註冊。我不知道如何/在哪裏檢查錯誤。登錄功能不能在PHP

我也嘗試更改託管配置的PHP版本，看看它是否會實際工作，但它沒有。

有人請指教

以下是我的登錄頁面的完整代碼。

<?php require_once('Connections/dbconnect.php'); ?> 
<?php 
if (!function_exists("GetSQLValueString")) { 
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{ 
    if (PHP_VERSION < 6) { 
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; 
    } 

    $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue); 

    switch ($theType) { 
    case "text": 
     $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL"; 
     break;  
    case "long": 
    case "int": 
     $theValue = ($theValue != "") ? intval($theValue) : "NULL"; 
     break; 
    case "double": 
     $theValue = ($theValue != "") ? doubleval($theValue) : "NULL"; 
     break; 
    case "date": 
     $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL"; 
     break; 
    case "defined": 
     $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue; 
     break; 
    } 
    return $theValue; 
} 
}

本地系統和託管系統上的密碼通常有區別。你嘗試過嗎？連接字符串是否相同？ – Difster

此外，使用'msyqli_real_escape_string' - 如果您在PHP 7.x中託管，mysql已被棄用，並且您必須使用mysqli或PDO。 – Difster

出現了什麼錯誤？也許你的dbconnect上有一些東西。您使用已經被棄用的原生連接 – smzapp

您確定Connections/dbconnect.php在服務器上嗎？看起來你無法獲得數據庫連接。
