我已经用 php 构建了一个注册系统，它应该通过我的工作 apache 和 mysql 服务器与 phpmyadmin 连接。但是，当我单击“注册”旋钮时，不是打开/运行 signup.inc.php，而是如下所示：

下面分别是：dbh.inc.php、signup.inc.php、index.met.interne.header.en.footer（主文件）和signup.inc.php。很抱歉 ULing 这么多文件。

<?php

$dbServername = "localhost";
$dbUsername = "root";
$dbPassword = "";
$dbName = "login.system";

$conn = mysql_connect($dbServername, $dbUsername, $dbPassword, $dbName);
<?php

if (isset($_POST['submit'])) {

	include_once 'dbh.inc.php';

	$uid = mysql_real_escape_string($conn, $_POST['uid']);
	$kvk = mysql_real_escape_string($conn, $_POST['kvk']);
	$bedrijfsnaam = mysqli_real_escape_string($conn, $_POST['bedrijfsnaam']);
	$merknaam = mysql_real_escape_string($conn, $_POST['merknaam']);
	$email = mysql_real_escape_string($conn, $_POST['email']);
	$wachtwoord = mysql_real_escape_string($conn, $_POST['wachtwoord']);

	//Error handlers
	//Check for empty fields
	if (empty($kvk) && empty($bedrijfsnaam) ) {
		header("Location: ../signup.php?signup=empty");
	exit();
	} else {
	//Check if input characters are valid

经过进一步调查，我们发现服务器配置有点不对劲，我们不得不做一些改变。重定向未使用 HTTP 协议，也未在打开时执行文件。

一旦我们弄清楚了，与数据库的连接就没有建立起来，因此mysqli_real_escape_string()返回了空值。为了解决这个问题，我们确保其中的所有信息mysqli_connect()都是正确的，而事实并非如此。更不用说所有文件中的参数顺序错误（mysql/mysqli 不同）。

最后，由于某种奇怪的原因，users在数据库中找不到该表，因此我们不得不创建它并修复 SQL 查询，因为没有插入数据。

其余的是一些逻辑错误和类似的东西，但这里没有清晰的方法来解释这一切。问题已成功解决。

数据已正确发送，但一些服务器配置错误和编程错误导致了所描述的所有问题（以及其他一些问题）。
