genie's having problem in downloading FTP File - help me out

I am usng ftp_get function. ftp_get($ftp,$select_file,$select_file,FTP_BINARY) even though i give any other dir /file name in place of the temporary file it gives the error in opening file. soemtimes it executes the cmmand but when searched no downloaded file founds. basically my problem is that after entering the user name and the password the user should be able to view his files (only his files) and all the file should be hyperlinked to their respective file addresses. so that they acn download the file by clicking on the file link. please help me out. or give any other suggestion to implement above thing. any suggestions would be highely appreciated. :-)
