I have a page like so:
http://sitename/gallery.php?page=2
It has pagination links at the bottom by which we can browse. Everytime the page numbers are clicked, it would send a GET request with parameters page=1 or page=2 and so on ...
When I store these values to $page
from teh $_GET
variable, it is a string value. I can convert it to an integer using (int)
like this:
if(!empty($_GET['page'])){
$page = (int)$_GET['page'];
echo "Page Number: ".$page;
}
But how can I make sure that the value passed is an integer only and not other crap?
