Case insensitive ksort

[Christoph Boget]

I looked in the docs but didn't see anything regarding case
insensitivity and I fear the functionality doesn't exist. I'm just
hoping I'm looking in the wrong place.

Is there a way to get ksort to work without regard to case? When I
sort an array using ksort, all the upper case keys end up at the top
(sorted) and all the lower case keys end up at the bottom (sorted).
Ideally, I'd like to see all the keys sorted (and intermixed)
regardless of case. Am I going to have to do this manually? Or is
there an internal php command that will do it for me?

thnx,
Christoph

Is this what you are looking for?

<?php

$yourarray = array();

$sorted = natcasesort(array_keys($yourarray));

foreach ( $sorted AS $key ) {
echo $yourarray[$key];
}

?>

uksort($array, 'strcasecmp');

I don't have time to look up in the manual but I don't remember a case
insensitive ksort().

I think there's a uksort() where you could specify your own sorting
parameters for the keys.

Also, you could create the array with keys run through strtoupper() or
strtolower(). If you need the proper upper/lowercase version too, you
could store that separately within the array.

Just some thoughts on how you could do this. good luck!
