[pmwiki-users] New Cookbook : CurrentVisitors

[Patrick R. Michaud]

Another hint:  Use PmWiki's mkdirp() function instead of
mkdir() to create the directory.  This will make sure that 
the CurrentVisitors directory exists with the appropriate 
permissions (as well as prompt the administrator to create the 
directory if it's needed).

Also, instead of using fopen/fclose to mark the files, just
use PHP's touch() function:

    $file = "$CurrentVisitorsDirectory/" . 
            preg_replace('/\D/', '_', $_SERVER['REMOTE_ADDR']);
    touch($file);
