Thanks for your help, folks.  This seems to do the trick:


// executes $cmd as a separate process and returns the following:
//	$result			= null if unable to start process, else:
//	$result["exit_code"]	= exit code returned by $cmd
//	$result["stdout"]	= stdout written by $cmd
//	$result["stderr"]	= stderr written by $cmd
function sysCmd($cmd)
{
	$result = array();
	$descr = array();
	$descr[0] = array("pipe", "r");		// stdin
	$descr[1] = array("pipe", "w");		// stdout
	$descr[2] = array("pipe", "w");		// stderr
	$proc = proc_open($cmd, $descr, $pipes);
	if (is_resource($proc))
	{
		fclose($pipes[0]);		// no stdin data
		$result["stdout"] = stream_get_contents($pipes[1]);
		fclose($pipes[1]);
		$result["stderr"] = stream_get_contents($pipes[2]);
		fclose($pipes[2]);
		$result["exit_code"] = proc_close($proc);
	}
	return $result;
}
