PHP - Use isset inside function not working..?
- by pnichols
I have a PHP script that when loaded, check first if it was loaded via a POST, if not if GET['id'] is a number.
Now I know I could do this like this:
if(isset($_GET['id']) AND isNum($_GET['id'])) { ... }
function isNum($data) {
$data = sanitize($data);
if ( ctype_digit($data) ) {
return true;
} else {
return false;
…
