I'm confused as to what you're really after.  Wouldn't a usage example 
apply to tips on passing arguments to a command line script?  Arguments 
for such scripts are found in $_SERVER['argv'], not STDIN.

As far as STDIN goes, I'm used to reading it via fopen() then fgets().

So, a quick and dirty example...


if ( empty($_SERVER['argv'][1]) ) {
    $_SERVER['argv'][1] = '';
}

switch ($_SERVER['argv'][1]) {
    case 'blah':
        $In = fopen('php://stdin', 'r');

        while ( !feof($In) ) {
           // do blah
        }
        break;

    default:
        echo 'usage...';
}

Enjoy,
