passthru($s [, &$i]) executes an external command $s and displays the raw output by passing the data back directly without any interference. $i stores the return status of the Unix command. No value is returned. system($s [, &$i]) is identical to passthru() but tries to flush the web server’s output buffer after each line of output. The latter function returns the last line of command output.
