"Members who have read thread" question

[MarkFL]

This is what I wound up doing, only executing the sort if the user can see the data and I wanted a case-insensitive sort as well:

PHP Code:

if ($show['wrt'])
{

    if (!function_exists('wrt_compare_username'))
    {
        function wrt_compare_username($u1, $u2) { return strcmp(strtolower($u1['username']), strtolower($u2['username'])); }
    }

    $wrtlist[count($wrtlist)]['comma'] = ',';
    usort($wrtlist, 'wrt_compare_username');
    $wrtlist[count($wrtlist)-1]['comma'] = '';
} 


I used usort() so that the keys would not be preserved, otherwise you wouldn't know which is last after the sort.

I have created a product based off of the ideas in this thread here (thank you Kevin and Paul for your contribution ):

Sort Who Read Thread Users

That product will allow you to sort the users either by userid, username, or dateline.
