Re: Writing to process STDIN and reading its STDOUT from PHP4?

Thanks Robert, However, those functions deal with PHP's own stdin/stdout. What I am trying to do is write to STDIN of a process started by PHP and then read the process STDOUT. So far, the only way I know how to do this is to first stick the STDIN to a file, and then use popen to call the process as process < TMPFILE and then to read the output via a file descriptor.
