PHP Page Not Showing Up On Browser And Can't See Source Code

我正确地运行了这个php文件，它昨天出现在浏览器上，但是今天，突然之间，我无法正确看到该文件，也无法通过浏览器在源代码中找到代码。

另外，这是我遵循的教程：https://www.youtube.com/watch?v=hAkKC8DKN9A

这是代码：

<?php
error_reporting(E_ALL ^ E_NOTICE);
session_start();
?>
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Member System - Log In</title>
</head>
<body>
    <?php
    $form = "<form action='./login.php' method='post'>
    <table>
    <tr>
        <td>Username:</td>
        <td><input type='text' name='user' /></td>
    </tr>
    <tr>
        <td>Password:</td>
        <td><input type='password' name='password' /></td>
    </tr>
    <tr>
        <td></td>
        <td><input type='submit' name='loginbtn' value='Login' /></td>
    </tr>
    </table>
    </form>";
    if ($_POST['loginbtn']) {
        $user = $_POST['user'];
        $password = $_POST['password'];
        if ($user) {
            if ($password) {
                require("connect.php");
                password = md5 (md5("kjfiufj".$password."Fjf56fj"));
                echo "$password";
                $query = mysql_query("");
                mysql_close();
            }
            else 
                echo "You must enter your password. $form";
        }
        else
            echo "You must enter your username. $form";
    }
    else 
        echo $form;
    ?>
</body>
</html>

PHP 解析错误：语法错误，第 41 行出现意外的"="。取代

password = md5 (md5("kjfiufj".$password."Fjf56fj"));至

$password = md5 (md5("kjfiufj".$password."Fjf56fj"));
