$_POST vs. $_SERVER['REQUEST_METHOD'] == 'POST'
<p>Some guy called one of my Snipplr submissions "crap" because I used <code>if ($_SERVER['REQUEST_METHOD'] == 'POST')</code> instead of <code>if ($_POST)</code></p>

<p>Checking the request method seems more correct to me because that's what I really want to do. Is there some operational difference between the two or is this just a code clarity issue?</p>
