According to the PHP documentation on isset(), the function returns true if the variable has a defined value. This would be equivalent to the defined function of Perl:

    $comment= param('comment')
        if defined param('comment');

I think the $_POST hash in PHP is populated by HTTP POST parameters - you would have to check that too.
