Values not generating for last month in datetime php - php

Question

I am trying to get the number of sat&sun for each month between two given dates.
eg: For start_date as 5-Jul-2015 and end_date as 29-Aug-2015 I need to get 7 sat&sun in Jul and 9 in Aug.
So far I am getting values till the second last month ie: not getting Aug.
What to do?
Code
$countSat = 0;
$countSun = 0;
$start = new DateTime('05-07-2015');
$month = $start->format('n');
$end = new DateTime('29-08-2015');
$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($start, $interval, $end);
$i = 0;
foreach ($period as $dt) {
if ($month != $dt->format('n')) {
$results[$i] = $countSun + $countSat;
$i++;
$countSun = 0;
$countSat = 0;
}
if ($dt->format('N') == 7) {
$countSun++;
}
if ($dt->format('N') == 6) {
$countSat++;
}
$month = $dt->format('n');
}
echo '<pre>';
print_r($results);

You are forgetting to add the results after the loop is done. The month will only change from 7 to 8 inside the loop.
Thus the days of the last month are being counted but never added.
$countSat = 0;
$countSun = 0;
$start = new DateTime('05-07-2015');
$month = $start->format('n');
$end = new DateTime('29-08-2015');
$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($start, $interval, $end);
$i = 0;
foreach ($period as $dt) {
if ($month != $dt->format('n')) {
$results[$i] = $countSun + $countSat;
$i++;
$countSun = 0;
$countSat = 0;
}
if ($dt->format('N') == 7) {
$countSun++;
}
if ($dt->format('N') == 6) {
$countSat++;
}
$month = $dt->format('n');
}
$results[$i] = $countSun + $countSat;
echo '<pre>';
print_r($results);
