Answer 1

之后

$email = $_POST['email'];
$email = strip_tags($email);

你可以像这样检查

$is_valid_email = filter_var($email, FILTER_VALIDATE_EMAIL);

这将返回true或false。

然后如果$is_valid_email为false，请确保此部分无法执行：

} else {
   $success=mysql_query("INSERT INTO users (username,password,email,name) VALUES ('$username','$password','$email','$name')");
}
