Use global. Read the docs about variable scoping.
If you use php >=4.1.0 then use $_POST, $_GET,... they not need to use global. Global
scope.
<?
function show($name)
{ global $HTTP_POST_VARS;
$cnt = count($HTTP_POST_VARS[$name]);
echo "Count for $name is $cnt";
echo "<br />";
}
show("countries");
show("cities");
?>
