It's common mistake what you are doing...
the first thing should be to test if there is such key in array:
if (array_key_exists('cmd',$_POST))
{
}
this means to test it the variable exists, then you can test if it was set

seems lengthy. is there a way around this?
i tried using $cmd = @ $_POST['cmd'];
to suppress errors but didnt seem to have ay effect.
still if(isset($_POST['cmd'])) { $cmd = $_POST['cmd']; }
is the only (really) correct way. All others throw notices of undefined indices, which you *should not* ignore! You can't shorten it, you can't even wrap it in a function... it's simply tough luck
Please correct me if I'm wrong (and maybe this is what you mean by "(really)") but I think even Rasmus recommends:
<?php
if(!empty($_POST['cmd'])) { // stuff }
?>
I'm using the following code to test this:
<?php
error_reporting(E_ALL);
if(!empty($_POST['cmd'])) { echo "set and not empty<br />"; } else { echo "empty and/or not set<br />"; }
?>
