How do I accept passed GET or POST values case insensitively?
Like sample.php?OrderBy=asc will still be the same as sample.php?orderby=asc or sample.php?ORDERBY=asc
Is there a means of achieving the above efficiently?

Not sure of a good solution, but I ran into a problem like that where the hashed password has gotten lower-cased and was unable to use it; so be careful, and I would suggest looking to see why this happens in the first place; usually when converting from HTTP to HTTPS (or back), the URL gets lower-cased.BeemerGuy– BeemerGuy2010-11-18 03:32:02 +00:00Commented Nov 18, 2010 at 3:32

3well im working on an API where the system previously serves other API clients that use uppercase and recently we made API some changes including the decision to honor lower-cased parameters. so in order to maintain backward compatibility with the previous API users, i am faced with this kind of problem.VeeBee– VeeBee2010-11-18 03:40:38 +00:00Commented Nov 18, 2010 at 3:40

You could use array_change_key_case() to create a copy of $_GET with either all uppercase or all lowercase keys.
$_GET_lower = array_change_key_case($_GET, CASE_LOWER);
$orderby = isset($_GET_lower['orderby']) ? $_GET_lower['orderby'] : 'asc';
echo $orderby;
(I say "create a copy" simply because I don't like polluting the original superglobals, but it's your choice to overwrite them if you wish.)
For that matter, it'd still be better if you just stick to case-sensitive matching since it might be easier on both search engine and human eyes, as well as easier on your code... EDIT: OK, based on your comment I can see why you'd want to do something like this.

What is the reason to change case?

When launching the default web browser with a Shell command from VBA, I've had the url mysteriously changed to all lower case if the browser is the Windows 10 Edge browser. But not on all Windows 10 computers, only some.

I have been working on an API that needed to recognize that
ID, Id and id are the same... Thanks @BoltClock
