有什么方法可以使用吗
我有下面的代码：

<?php
if(isset($_GET['i'])){
echo '<script type="text/javascript">alert("INFO:  ' . $_GET['i'] . '");</script>';
}
?>

根据您的错误代码显示消息：

<?php
    if(isset($_GET['i'])){
        switch($_GET['i']) {
            case 100:
                $errorMsg = "Please use a valid email"; // For example
            break;
            case 200:
                $errorMsg = "Email already in use";
            break;
            default:
                // If $_GET['i'] has an unexpected value
                $errorMsg = "Oops, there was an unknown error";
            break;
        }
        echo '<script type="text/javascript">alert("INFO:  '.$errorMsg.'");</script>';
    }
?>
