Problem with validation, change little codes

if ($link->type!="-") $replacement = $replacement.'target="'.$link->type.'"';
					if ($link->rel!="-") $replacement = $replacement.'rel="'.$link->rel.'"';
					$replacement =	$replacement.'title="'.$link->anchortext.'" >'.$isFind[0].'</a>';

This code has problems with validation w3c, how to validate it? ??
