Question

我最近在尝试登录我的网站时遇到此错误。我的PHP脚本在涉及验证密码的if语句时停止。我的托管服务提供商说问题出在我身上，但是我的代码可以在我的测试服务器上运行，也可以在其他提供商的主机服务器上运行。我对为什么停止感到困惑。任何帮助都将是惊人的！它进入login-processing.php页面，显示回显语句直至“绑定stmts”，然后停止。

控制台错误：

无法加载资源：服务器的状态为500（内部服务器错误）

PHP：

    <?php
    echo "before submit";
if (isset($_POST['submit']))
{
    echo "submitted";
    require_once 'db.php';
    $uid = $_POST['username'];
    $pwd = $_POST['password'];
    echo $uid . "  " . $pwd;
    if (empty($uid) || empty($pwd)) 
    {
        echo "fail1";
        exit();
    }
    else
    {
        echo "<br> <br> in query";
        $sql = "SELECT * FROM users WHERE uid = ?;";
        $stmt = mysqli_stmt_init($connection);
        if (!mysqli_stmt_prepare($stmt, $sql))
        {
            echo "fail2";
            exit();
        }
        else
        {
            echo "<br> <br> in final query";
            mysqli_stmt_bind_param($stmt, "s", $uid);
            mysqli_stmt_execute($stmt);
            echo "<br> <br> binding stmts";
            $result = mysqli_stmt_get_result($stmt);
            if ($row = mysqli_fetch_assoc($result))
            {
                echo "<br> <br> verifying password";
                $pwdCheck = password_verify($pwd, $row['pwd']);
                if ($pwdCheck == false) 
                {
                    echo "fail3";
                    exit();
                }

                {
                    echo "<br> <br> starting session";
                    session_start();
                    $_SESSION['id'] = $row['id'];
                    $_SESSION['uid'] = $row['uid'];
                    $_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];
                    $_SESSION['initiate'] = rand(0, 1000000);
                    header("Location: http://blog.com.au/blog.php");
                    exit();
                }
                else

HTML：

<form action="login-processing.php" method="post">

    <input type="text" name="username" placeholder="Username"><br>

    <input type="text" name="password" placeholder="Password"><br>
