File upload Change file name

Question

I found an appropriate script that lets me upload multiple image files to the server. What i am trying to do is just change the name of the files and have no idea how i would do it using this code. Could someone please tell me what i need to do? Thanks

Answer 1

Try to change

if(@copy($_FILES['userfile']['tmp_name'][$i],$upload_dir.'/'.$_FILES['userfile']['name'][$i]))

For

if(@copy($_FILES['userfile']['tmp_name'][$i],$upload_dir.'/'.'NAME OF YOUR FILE']))
