note 102757 added to function.ctype-alnum

I think your test <?php if(!ctype_alnum(str_replace($aValid), '', $sUser)) ?> has the brackets in the wrong place. the one after $aValid should be moved to the end. Adding a few spaces to aid legibility, should it not be: <?php if( !ctype_alnum( str_replace($aValid, '', $sUser) ) ) ?> Aside from that, a useful technique, thank you.
