Recently I needed to add a certain amount of weekdays onto a date using php 5.3.
I wrote this simple function which has two parameters, the amount of weekdays I want to add and the date I want to add them to as an instance of DateTime as follows:
/** * @param int $weekDays * @param DateTime $date * @return DateTime */ public function addWeekdaysToDateTime($weekDays, DateTime $date) { $days = 0; //only increase the day count for weekdays while ($days < $weekDays) { $date->modify("+1 day"); //if we're now on a weekday, increase the weekday counter if (!in_array($date->format("D"), ['Sat', 'Sun'])) { $days++; } } return $date; }
