$num2= mysql_num_rows($query);
while($rs=mysql_fetch_array($query)){
$sort2[]=array(
'id' => $rs['id'],
// 'product_name'=> $rs['product_name'],
'product_name'=>preg_replace("/($keyword)/i","<font color=red><b>//1</b></font>",$rs[product_name]),
'product_hao' => $rs['product_hao'],
'picture' => $rs['picture'],
'product_xin' => $rs['product_xin']
);
// print_r($sort2);
