you can delete a file with a normal unlink function in the php api

You can make a script delete itself with ftp_delete! It's pretty useful when creating an install script which you want to destroy at the end of the installation to prevent it from being run later. On Linux machines, very often the user uploads third party scripts, and gets asked to CHMOD this and delete that manually because the webserver user is different from the FTP user ; make them enter their FTP info and get rid of the tedious file manipulation step! Be careful, though. You will need to flush the output buffer and call ftp_delete at the end of the script, or else the script will die before it fully executes. Look up ob_end_flush for more info.
