How to change the value of uploaded file?

[Persis]

Hello,

I have a small upload script which uploads example.gif to the specific directory.
Now I want to make something that when $user wants to upload a file, it automatically renames the file and save it as $user.gif instead of example.gif

Im trying to integrate the upload script with another script.

Any help is appreciated.

rename()
or
move_uploaded_file()

So it should be:

rename($file_name, $user.gif); ??

sorry im noob 🙁
