Answer 2

You can use FIND_IN_SET() to solve this.

if($array)
{
    $this->db->group_start();
       $this->db->where("FIND_IN_SET('$array[0]', title) != ",0);
       for($x=1; $x < count($array); $x++)
       {
         $this->db->or_where("FIND_IN_SET('$array[$x]', title) != ",0); 
       } 
    $this->db->group_end();
}
