我是一个新手，花了3个多小时试图从上传的文件中找到文件名、文件大小、路径。但这张表格是以我无法理解的方式进行的。我需要存储在数据库中的文件名、文件大小和路径变量。如何在下面的代码中实现$sql插入：

                                        // filesystem path


  $web_upload_dir = "/aeu"; // Directory for file storing`
                      // Web-Server dir 

 /* upload_dir is filesystem path, something like
 /var/www/htdocs/files/upload or c:/www/files/upload

    web upload dir, is the webserver path of the same
     directory. If your upload-directory accessible under 
    www.your-domain.com/files/upload/, then 
   web_upload_dir is /files/upload

这是很多代码…也许吧？@sascha谢谢。我知道如何插入。只是我不知道如何从这个上传脚本中提取我需要的信息，以便我可以将其插入数据库。谢谢！！！成功了！我有一个后续问题。知道如何获得大小类型，如kb、md？thx！以字节为单位返回大小。

move_uploaded_file($_FILES['file']['tmp_name'], $upload_dir.'/'.$filename);



$size = filesize($upload_dir.'/'.$filename);
$path = $upload_dir.'/'.$filename;

mysql_connect(YOUR_HOST, YOUR_USERNAME, YOUR_PASSWORD);
mysql_select_db(YOUR_DATABASE);

mysql_query('INSERT INTO your_table SET filename=$filename, size=$size, path=$path');
