Question

I am getting a variable from $_GET['category']. This is always supposed to be a integer. So when I set the variable I use:

$category=settype($_GET['category'], "int");
// Also tried
$category=settype($_GET['category'], "integer");

However, this always returns 1. They are numbers in the query string for example:

http://domain.com/example.php?category=57

When I echo $category it always returns 1. No mater what ?category= has behind it for a number.

Any help would be appreciated! Thank you!

Answer 1

settype modifies the type of the variable. You’re using it as if it would return a new variable.

However, settype returns true if the type change was successful, and false otherwise. You’re seeing the result 1 since that’s the string representation of true.

You should either use casting, or intval:

$category = (int) $_GET['category']; // or ...
$category = intval($_GET['category']);
