getting buffered output from exec?

[D. Alvarado]

Hello, I am running PHP 4 on Apache 1.31 for Fedora Core 2 Linux. I
run a process

exec("/bin/sh $my_script", $output, $return);

that takes about 15-20 seconds but produces multiple lines of output
throughout. Is there some way I can display the output as it comes
out as opposed to waiting until the process has finished and then
displaying the results?

Thanks, - Dave

Just popen() should do. Then use fgets() to read each line.
