What the client user wants now is to eliminate duplicating values. One thread I posted yesterday was solved but I repost it because of another problem... I revised the code for the table format but If there's someone out there who could help me in eliminating duplicate values

the full code was herehttp://www.daniweb.com/web-development/php/threads/367519

again please help me how to eliminate duplicating values... it goes like this way... I have sample peter griffin wherein stored in an array [peter] [griffin] and so on because of the explode function. I want now to know how to eliminate duplicating values because when I put Peter Griffin... the Peter Griffin is duplicated to show up

Here you can see I have executed query only once, and shortened for loop.

$operator="";
$condition="";
for( $i = 0; $i < count($words); ++$i ){
	$condition.=$operator." CONCAT(FirstName, ' ',LastName) LIKE  CONVERT(_utf8 '%".$words[$i]."%' USING latin1) COLLATE latin1_swedish_ci";
	$operator=" OR ";
}
$sql = "SELECT *,CONCAT(FirstName, ' ',LastName) as fullname FROM `ajax_demo_table`   ";

if ($condition!="")
$sql .= " where ($condition) ";
