“解析错误：语法错误，意外$end”，用于我的uni注册分配[已关闭]

Question

我已经从代码中删除了所有html和所有error else语句，试图消除错误消息，但我似乎找不到它。错误总是发生在我的脚本的末尾。

有什么建议吗

        <?php

        if ( $_POST['registerbtn'] ) {
    //makes sure email, username is valid
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getretypepass = $_POST['retypepass'];

    if (!isset($getuser))
    {
        $error = "user not set ";
    } 

    if ($getuser) {
        if($getemail) {
            if($getpass) {
                if ($getretypepass) {
        require("connection.php");

                            $query = mysql_query("SELECT * FROM          users WHERE username ='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0) {
                            $query = mysql_query("SELECT * FROM users WHERE email ='$getemail'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0) {

尝试自动格式化（自动缩进）代码。如果您没有一个允许这样做的编辑器，那么可以使用Sublime Text或Notepad++这样的编辑器。：-）在类似的情况下，它将为您节省大量的时间；在这种情况下，不必试图定位问题，在自动形成问题后，问题将会出现在您的面前。：-）

我相信您在}之后缺少了大约六个关闭大括号（如果正确的话，我不确定我计算了未关闭的的数量）

{
    echo $form;
}

显然，如果是这种情况，就发生了严重的错误，可能需要更多的}来修复代码。
