case sensitivity question

[skiflyer]

Is there anyway to be case insensitive on query string?

i.e.

I don't care if it's
?Variable1=blahblahblah
or
?variable1=blahblahblah

And I can't just lowercase the whole line because I do care about the case in blahblahblah.

As is, I'm using
$_GET["Variable1"]

And I know I could do a
$myvar = $_GET["Variable1"];
if (!isset($myvar)) {$myvar = $_GET["variable1"];}

and so on to cover the likely cases, but I'd rather just have something which erases the case sensitivity of it all.

PHP variable names are case-sensitive. It's built into the language. Want the best answers? Ask the best questions:

But there's a way around everything

Guess I'm handparsing the query string.

If you're putting that much effort into doing something the language wasn't designed for, you have to ask yourself two things:

1) Are you using the right language?
2) Why not just accept what the normal is (ie why bother making it case-insensitive)?

Well, the first yes, mostly because in php this is actually an incredibly easy thing to do.

$_SERVER["QUERY_STRING"] holds the string
then I can split it into an associative array, and make all the keys lower case using lcase it is I believe, and now I have a different associative array that works just like $_GET[]

And the second, I may..., but when a page has to receive query strings sent from emails sent by 3 different departments, I'd rather be ready for everything rather than assume they'll format their strings properly.

just in case anyone else wants this functionality, PHP actually makes it ridiculously easy... and it works with either $_POST or $_GET...

$_GET = array_change_key_case($_GET, CASE_LOWER)

or CASE_UPPER if you prefer
