Efficient Way to Log

[KGodel]

All good tips, thanks guys. Is there any function within VB I can use that can get a UserID based on a username without needing the query the database at all? That would be the ideal, but if not I'll just have to double clean the array. Here is what I have:

PHP Code:

    $vbulletin->input->clean_array_gpc('p', array(
        'points'         => TYPE_UNIT,
        'users'          => TYPE_STR
        )); 


PHP Code:

    $ausers = $db->escape_string($vbulletin->GPC['users']);
    $addusers = explode(";",$ausers); 


So addusers is an array. Obviously I'll have to turn it into a list before I can use it in the manner I want (basically query the database to get the ID of anyone whose username is in this list of names). If it's safe after these cleaning methods then I'll be a bit more confident.
