[Erw-devel] PEAR HTTP.php

In case anyone's doing multilingual apps, you may want to know that various browsers handle their language settings differently. This causes problems with using HTTP.php's negotiateLanguage() function. Specifically, some browsers handle US English thus:
en-us, en-US, EN-US
And not all of these will work -- the function as coded (at least with my "stock" RH9 system's RPM) does a case _sensitive_ comparison (bad idea). To handle it "properly" (per RFC), you need a case insensitive comparison, as provided by the patch below. It's been reported to PEAR, but never fixed, as far as I know.

diff HTTP.php.orig HTTP.php
>        $supported = array_change_key_case($supported, CASE_LOWER);
<                    $l = $accepted[$i];
>                    $l = strtolower($accepted[$i]);
