Filter a 2d array (query result set) by multiple conditions

Is there any solutions out there, that make it possible to search in a query.

Example:

I've this simple query:

$this->db->where('start >=',time());
$this->db->where('end <=',strtotime("+1 month"));
$result = $this->db->get('bookings');

What I then want it to be able to make a search that looks like my query above, but which doesn't search in the database, but in the $result results.

So it should be possible to do something like:

$where = array(
  'start >=' => time(),
  'end <=' => strtotime("+1 day")
);
$get_result_info_by_search = $this->Search_model->get_stored_results($result, $where);

The goal is to reduce the number of calls to the database, because my interval is always the same (I loop through a date range and make the same call for instance 31 times (if 31 days)

This can be done quite easily by looping through the rows and testing 'start' and 'end' values.

/**
 * @param CI_DB_result instance $result
 * @param array $where with two keys, 'start' and 'end', containing timestamp values, ie. 
 * $where = ['start' => time(), 'end' => strtotime("+1 month"));
 * @return mixed An array of db row objects or NULL if nothing matches
 */
public function get_stored_results($result, $where)
{
    $rows = $result->result();
    foreach ($rows as $row)
    {
        if($row->start >= $where['start'] && $row->end <= $where['end'])
        {
            $matches[] = $row;
        }
    }
    return isset($matches) ? $matches : NULL;
}

If you would rather get back an array of row arrays

public function get_stored_results($result, $where)
{
    $rows = $result->result_array();
    foreach ($rows as $row)
    {
        if($row['start'] >= $where['start'] && $row['end'] <= $where['end'])
        {
            $matches[] = $row;
        }
    }
    return isset($matches) ? $matches : NULL;
}
