Here is a way to declare global variable variables using a function.
This particular example handles an array that contains names of $_POST items. This is to avoid the
notices that php gives when checking an unused $_POST.
<?php
function check ($inputs) {
foreach ($inputs as $input) {
global $$input;
$$input = isset($_POST[$input]) ? $_POST[$input] : "";
}
}
?>
