But be careful with this...
$i="4";
if($i === intval($i)){
// this will not happen
}
Also keep in mind that values that are supplied via _GET, _POST, _COOKIE
are strings, not their representative types...
Therefore:
call page: page.php?i=4
if($_GET['i'] === intval($_GET['i'])){
// this will not happen
}
