printing out messages while processing a file

Hi there, I am writing a backup_restore file which creates directories and picture files with different resolutions out of an original file. After each process completes I would like to print out a [ok] message, but unfortunatelly it prints those msg out only when the script is completely through and done. How can I echo out status messages? The script is run by console php. ( I also noticed that \n or <br> does not work for the console?!) Thank you for any help, Merlin
