echo '<br>'.$nextOccurrence;
// 2018-08-08

You can also specify the preferred day of the month Eg. "first monday":

$nextOccurrence = DateFrequency::nextOccurrence('08-05-2018', '3', 'months', 'third wednesday');

// 2018-08-15

To change the format, add it to the parameters:

$nextOccurrence = DateFrequency::nextOccurrence('08-05-2018', '3', 'months', 'third wednesday', 'Ymd');
echo '<br>'.$nextOccurrence;
// 20180815
