Copy/Backup Folder

Is there a way I can copy a certain folder and its contents to a users computer using php?

If you use the user's computer as an FTP server you can. You also could zip it up and serve it for downloading.

I'm not sure if we're talking about the same thing here.

When a user registers on my website it automatically creates a folder for them. Every time they upload a file it gets put into their folder. I want the user to be able to click a button in their cp and download a backup of all their files. Is this possible?

Tree is right. You could use the ZIP archive module for doing that. The Linux method looks far easier to me, as given as an example on the PHP.net page:

php Code:

// Get the date
$date = date("m-d-y");

// Make Zip name
$zipname = "archive/site-script-backup." . $date . ".zip";

// Make a zip file
$cmd = `zip -r $zipname *`;

I wouldnt create folders for everyone, that way everybody can find files of another user. I would save files by a file_id and link the user with a file by a database. That way you won't have to worry about all the file handling, just uploading and deleting files. "Eitje" as we would say here in the netherlands :>

Thanks for that :) I was a bit confused when you mentioned FTP.

As for people being able to find the files of other users, it shouldn't be a problem because the files will only be images to display in a gallery anyway.

No problem. I originally thought you wanted to build a script that backed things up to just your computer.
