number of rows in a table

Answer 1

conncet.php

connect();
  }

  private function connect()
  {
     $this->link = new mysqli($this->host, $this->user, $this->pass, $this->db);
     return $this->link;
  }

 public function select($query)
 {
    $result = $this->link->query($query) or die($this->link->error.__LINE__);
    if($result->num_rows > 0)
    {
      return $result;
    } 
    else 
    {
        return false;
    }
}
?>

Now action.php where query can be done as follows :

 $db = new database();
 $query = "SELECT COUNT(*) FROM accounts";
 $row = $db->select($query)->num_rows;
 echo $row;
?>
