Converting a dos console batch file to a php shell script

Hi everyone, I've been searching for info to help me troubleshoot an issue I'm having with displaying output to the console during script processing, but I'm not having much luck. I'm hoping someone can shed some light on this or point me in right direction. I have a foreach construct that loops through an associative array and calls a nested function. Inside the foreach loop I would like to display the current array information that is being processed prior to passing to the nested function call. The problem I'm running into is that the output to the console window is delayed till after the forloop as completed, as if it's being buffered then flushed at the end. Any ideas how I can display information as processing occurs? Thanks in advance, Jim
