yup, treat $_POST as you would an array because it is an array

example
foreach($_POST as $key => $item)
{
$$key = trim($_POST[$key]);
}

key is a variable variable

it would be the equivalent of this

$apple = $_POST['apple'];
$orange = $_POST['orange'];
$pear = $_POST['pear'];

etc..

with the loop above you don't have to go thru the process of calling each one out
it's done throu the loop - hope that makes sense
