Your code have some errors, but if I undestood right...

$ref = 'url.php?t=4&p=5&sid=ddf175fd02216cbe9fab9a4b528d7185&hilite=2c23tra#link';
$params = array('sid','t','p','hilite');

function cleanQueryString($ref, $params = NULL){
	$newparams = array();
	preg_match_all('|([^?&#=]+)=([^?&#=]+)(#{0,}[^?&#=]*)|', $ref, $out, PREG_SET_ORDER);
	
	foreach($out as $elem)
		if(!in_array($elem[1], $params))
			$newparams[] = "{$elem[1]}={$elem[2]}";  
	return implode('&',$newparams) . $out[count($out)-1][3];	
}

echo cleanQueryString($ref, $params);
