stdout as input

I've read the section in the docs about i/o streams and other related sections I was able to find but couldn't figure out how to do what I need. From the command line, I'm trying to pipe stdout in to my php script which should then see it as input. A simplistic example would be: echo bob | myScript.php In myScript.php, I'm doing: $handle = popen( 'php://stdin', 'r' ); echo var_export( $handle, TRUE ) . "\n\n"; I've also tried php://stdout and php://input. I also tried eschewing the php:// pseudo protocol and popen altogether and going with the STDIN and STDOUT constants. None of that worked. Is there a way I can pipe/redirect output from a command line uhh, command as input to my script? thnx, Christoph
