我一直在写一个HTML页面，我将在下面发布它，还将发布一个PHP脚本。但是当我使用HTML页面来编写信息并提交它时；在此服务器上找不到请求的URL"消息中，我将所有文件放在htdocs上的一个名为"的文件夹中；html"；，html页面被命名为"；索引"；并且该脚本被命名为"；测试"；，非常感谢您抽出时间。

PHP脚本
<?php
$handle = fopen("pruebapracticaHE.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "rn");
}
fwrite($handle, "rn");
fclose($handle);
exit
?>
您说过脚本名称是test.php
但我可以在HTML代码中看到，您在表单中设置了action="next.php"而不是action="test.php"，正确的代码是：
<form method="post" action="test.php">
