One way of using the CLI with PHP might be how the Developers of Eventum [1] 
are doing it. Another way could be how we are doing it for the TYPO3 
extension staticuploadrsync [2] and others. Checking if $_SERVER['argv'][0] 
is set and abort if not is always a good idea - which we haven't practiced in 
our extension ;-)

IMHO it is important to leave "#!/usr/bin/php" out of all scripts whoch should 
be used via CLI. There is no guarantee that the PHP CLI is located at the set 
position on each TYPO3 installation. Executing the file with the PHP CLI 
calling it by its full path is enough, e. g. "php /path/to/foo/bar.php", and 
avoids problems with different locations of the PHP CLI.
