致命错误语法错误，第23行

Question

这是怎么了？ 致命错误语法错误，第23行出现意外的'is'（T_STRING）

这是第23行，但我在这里没看到错吗？也许我一直盯着屏幕看很久，但对我来说看起来不错吗？

 else{
    (line 23)  $sql = $con->Something is wrong("SELECT id FROM users WHERE email='$email'");
        if ($sql->num_rows >0){
                        $msg = "Email currently exists";
                            }   

感谢大家的帮助。
