Hard to say, without knowing what the function is, what it's supposed to
do, who's calling it and why/when/where...
I'll take a wild stab at it, though, and suggest that if you care about
data types that much, then you should be converting your $_GET/$_POST to
(int) in the first place.
Plus, you should be converting your $_GET/$_POST data to (int) when
appropriate for your data scrubbing (security).
So, really, you should have:
<?php
$curval = (int) (isset($_GET['curval']) ? $_GET['curval'] : 0);
...
your_function(1337, $curval);
...
?>
Then you can use === in your function safely.
