Use mkdir and then put files in the folder

I have a website where users can create new "topics." Each topic has a folder (example: www.example.com/chemistry). I use mkdir() to create a new folder, but after it's created how can i put files in the folder so that when someone goes to the chemistry folder there's something to view? Since I haven't found much information on how to do this im guessing there is a more popular way.

is SO useing a CMS? becasue when i asked this question a "folder" appeared in the URL with my question ID.

What appears in the URL here is a URL. Repeat after me: http://stackoverflow.com/questions/8774143/use-mdir-and-then-put-files-in-the-folder is a URL! It has a hostname, it has a path, it may have query parameters. It does not have "folders"!

By default, in many web servers, a URL is mapped to a folder on the hard drive. But that's just one way to do it. When visiting a URL, the web server just receives the request "give me whatever site there is at URL http://stackoverflow.com/questions/8774143/use-mdir-and-then-put-files-in-the-folder". The web server may choose to answer this by looking into a folder whose name matches the URL. Or it may simply invoke a program, give it the URL and deliver back whatever response the program happens to spit out.

Try to learn about "URL rewriting" and "pretty URLs" and look into existing frameworks, since pretty much all frameworks implement this.

you can copy files:

copy($source, $desitination);

Upload files: see move_uploaded_file

Write files: see fwrite

PS. Just check if the folder exists first, eg if (file_exists($dir)) before calling mkdir($dir) or you will get warnings, or suppress mkdir() like this @mkdir() to silence any warnings
