PHP Sample Command Line Scrip

Some co-workers of mine didn't believe that PHP could be used from the command line. I was rather suprised by this, and thought others might be under the same impression. To help spread the word, here's a very simple example of a php script meant to be run from the command line.

<?php

if ($argc != 2 || in_array($argv[1], array('--help', '-help', '-h', '-?'))) {
?>

This is a command line PHP script with one option.

  Usage:
  <?php echo $argv[0]; ?> <option>

  <option> can be some word you would like
  to print out. With the --help, -help, -h,
  or -? options, you can get this help.

<?php
} else {
    echo $argv[1];
}
?>
