Php 警告：mysqli_stmt:：bind_param（）：变量数量与148上C:\User..\n中准备语句中的参数数量不匹配

我正在插入一个新的专栏collegename，branch，andgender，但突然它给了我这个错误

Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of 
parameters in prepared statement in C:\Users\Raj\PhpstormProjects\usercake\models
\class.newuser.php on line 148

那是什么意思

事实上，我在我的数据库中插入了一个新的专栏——学院、分校、年份和性别——一切都进行得很顺利，但当我注册自己时，它显示了一条消息：你的注册成功提交了，但突然它也显示了这条错误消息

以下是我的源代码：

你有10个？在prepare语句中，但在$stmt->bind_param上向它传递了6个变量。您必须传递和语句中完全相同的变量。您的绑定必须如下所示：

$stmt->bind_param('isisississ', $int1, $str1, $int2, $str2, $int3, $str3, $str4, $int4, $str5, $str6);

你最近不是问了同样的问题吗？你有更多的问题吗？它的意思就是：您的查询与您提供的参数不匹配。您只提供了6个参数，但占位符要多得多？我给您的是-1。理由：这样的信息很容易理解。我这么说是因为我是凭经验说话的——几年前我也有同样的错误信息，我能够自己解决它，而不用去网站，也不用花时间问问题。它告诉您变量的数量与语句中参数的数量不匹配。在那一点上，你唯一要做的事情是什么？为什么要去计算你在那一行绑定和执行的参数和变量的数量？这纯粹是懒惰，如果你不花时间调试，那有什么意义呢？你有10个？但是SSS I不是10个字符。。。。
