Writing mulitple output lines to single line

Hello all, I have tried looking through the previous messages, but I have yet to find anything that involves my specific problem. Maybe I am not searching for the correct terminology. I current have a php script that processes many files (6000+). When it is processing a file, it prints out what is going on with each file to a seperate line. What I want to do is OVERWRITE the output line for each file, and keep output to a single line. (Please see below for example) - I know it is possible to do this in bash, pearl and other scripting languages, but I have yet to figure out if it is possible in php. I have tried printing backspace characters (\b), the ascii equivalent, etc, but nothing seems to be working. If anyone has any solutions / suggestions, it would be most welcome. Example: Current screen (after 3 iterations): running cleanup... processing 1 of 6453: adding extensions / removing case. processing 2 of 6453: adding extensions / removing case. processing 3 of 6453: invalid extension - deleteing. Wanted screen (after 3 iterations): running cleanup... processing 3 of 6453: invalid extension - deleteing. (The content of the lines is unimportant, its the number of lines showing that is) Thanks in advance! - bob.
