网站描述：我的网站允许用户上传开源PHP网站项目。
您好我想知道在用户提交表单后如何生成像 sitename.com/projects.html?id=x 这样的网址。我该怎么做？我不知道从哪里开始。
new-project.html： 可让用户上传新的开源网络项目。

现在，您的表单提交到upload.php。因此，只需创建upload.php并处理POST请求并将信息保存在数据库中，然后将用户重定向到sitename.com/projects.html?id=x。您可以使用header('location: /projects.html')从PHP重定向用户。
现在代替projects.html，您需要projects.php（除非您有自己的路由系统或服务器设置，否则.html页面不会被PHP解析）。您需要/projects.php?id=3的PHP，因为您想动态生成该页面。
根据提供的ID动态生成/project.php?id=3页面。您可以使用$_GET访问ID的值。它的工作原理如下：
if(isset($_GET['id']) && ctype_digit($_GET['id'])){
# user have requested the page with a valid id (only number)
# now you can use $_GET['id'] to generate this page dynamically.
// your code here
// you probably want to authenticate users too
$requested_id = $_GET['id'];
}

当用户提交新项目时，生成一个随机数并将其作为带有项目详细信息的id保存到数据库中。因此，当有人前往sitename.com/projects.php?id=x时，它会在数据库中查找id并提供详细信息。
projects.php看起来像这样：
<?php
$id = $_GET['id'];
$sql = "SELECT * FROM projects WHERE `id`='{$id}'";
...
?>
