two methods in a class so close in what they do - php

Question

I have this class that has these two methods that are so closely related to the each other. I do not want to pass the flags so I kept them separate. I was wondering if there is a way to rewrite it so that I do not have to repeat so closely!
class Test extends Controller
{
public static function nonFormattedData($param)
{
$arr = array();
if (is_array($param)) {
$i = 0;
$sql = "
select *
from table1
where
";
if (isset($param['startDate'])) {
$sql .= " date_created between ? AND ?";
$arr[] = $param['startDate'];
$arr[] = $param['endDate'];
$i++;
}
if (isset($param['amount']) && !empty($param['amount'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " balance= ?";
$arr[] = $param['amount'];
$i++;
}
if (isset($param) && !empty($param['amount'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " balance= ?";
$arr[] = $param['amount'];
$i++;
}
if (isset($param['createdBy']) && !empty($param['createdBy'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " column2 like '%Created By: " . $param['createdBy'] . "%'";
}
$sql .= ' group by id.table1 ';
$rs = Query::RunQuery($sql, $arr);
foreach ($rs as $row) {
$records = new Account();
$results[] = $records;
}
return $results;
}
}
public static function formattedData($serArray, $orderBy = "giftcardaccount_id desc", $offset = 0, $limit = 10)
{
$arr = array();
if (is_array($param)) {
$i = 0;
$sql = "
select *
from table1
where
";
if (isset($param['startDate'])) {
$sql .= " date_created between ? AND ?";
$arr[] = $param['startDate'];
$arr[] = $param['endDate'];
$i++;
}
if (isset($param['amount']) && !empty($param['amount'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " balance= ?";
$arr[] = $param['amount'];
$i++;
}
if (isset($param) && !empty($param['amount'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " balance= ?";
$arr[] = $param['amount'];
$i++;
}
if (isset($param['createdBy']) && !empty($param['createdBy'])) {
if ($i > 0) $sql .= " AND ";
$sql .= " column2 like '%Created By: " . $param['createdBy'] . "%'";
}
$sql .= ' group by id.table1 ';
$rs = Query::RunQuery($sql, $arr);
return array("data" => $rs);
}
}
}

Answer 1

Why not have one method, but with an optional formatting options object/array?
public static function getData($params, $formatting = null) {
// continue as normal, adding formatting if it's there
}
