I would rather resign from using \DatePeriod if there are some non-standard requirements, and go with do...while loop. Something like this:
function dates_between(\DateTime $date_from, \DateTime $date_to) {
// always reset the time when working only with dates
$date_from->setTime(0, 0);
$date_to->setTime(0, 0);
$dates_between = [];
$current_dt = $date_from;
do {
$dates_between[] = [
'month_year' => $current_dt->format('d/m/Y'),
];
$current_dt->add(new \DateInterval('P5D'));
if ($current_dt->format('D') === 'Sat') {
$current_dt->add(new \DateInterval('P2D'));
}
elseif ($current_dt->format('D') === 'Sun') {
$current_dt->add(new \DateInterval('P1D'));
}
} while ($current_dt <= $date_to);
return $dates_between;
}
print_r(
dates_between(
new \DateTime('7/30/2018'),
new \DateTime('8/27/2018')
)
);
