从strtotime排除周末

I want to only show weekdays (Mon, Tue, Wed, Thur, Fri) in this snippet:

 <?=date('D M, d', strtotime('+3 days'))?>



I'm having trouble knowing what to search for in StackOverflow. My searches for "Calculate future date based on business days" or "Checking if date is weekend PHP" isn't yielding what I can understand to move forward.

Use Case: As a customer, I want to know how soon I receive service. This code will show me when I can get service, 3 weekdays days out (even on holidays).

I found this, http://php.net/manual/en/intlcalendar.getdayofweektype.php but I am still stuck :(

If you just want weekdays then strtotime can do this.

date('D M, d', strtotime('+3 weekdays'))
