Question

下午好，我刚刚开始使用PHP领域。该代码尚未完成，但是在尝试将其放入数据库之前，我希望它能够正常工作。但是我遇到了致命错误，如果继续操作，我将收到404 not found错误。致命错误是这样的：

致命错误：未捕获InvalidArgumentException：C：\ xampp \ htdocs \ login \ Classes \ domain.php：23中的无效语法：堆栈跟踪：

0 C：\ xampp \ htdocs \ login \ logins.php（25）：Whois-> __ construct（''）

第23行的C：\ xampp \ htdocs \ login \ Classes \ domain.php中抛出1个{main}

有问题的代码行是这样的：

$whois_answer = $domain->info();

我真的不知道该如何解决...

<?php
            require ("Classes/domain.php");

            $search = "";
            echo "<form action='login.php' method='get'>";
            echo "<p>Qual é o domínio que deseja procurar?</p><br>";
            echo "<input type='text' name='search' value=''><br><br>";
            echo "<input type='submit' name='search2' value='Procurar'>";
            echo "</form>";
            if (!empty ($_GET['search'])){
                $search = $_GET['search'];
            }
            $sld = $search;
            //var_dump($search);

            //$sld = 'larousse.fr';
            $domain = new Whois($sld);

            $whois_answer = $domain->info();

            $answer= preg_split("/\r\n|\n|\r/", $whois_answer);

和domain.php：

第一-感谢您为我提供帮助。第二-解决方案是：

echo "<form action='logins.php' method='get'>";

在logins.php中，该文件拼写错误，我将login.php代替了logins.php;

并且if太短了，如果我将程序的其余部分包括在内，就可以了。
