Working days (Mon-Fri) in PHP

Question

Is there a way to use strtotime to add working days (Monday to Friday) to a date? Or some other method? What I want to do is:

date ( 'Y-m-j' , strtotime ( '+3 working days' ) ) 

Answer 1

If you are limiting to weekdays use the string weekdays.

echo date ( 'Y-m-j' , strtotime ( '3 weekdays' ) ); 

This should jump you ahead by 3 weekdays, so if it is Thursday it will add the additional weekend time.

Answer 2

I have found this buggy when needing a larger amount of weekdays. I was looking for X amount of business days after the 1st of the current month.

Looked great at first until after adding > 5 business days (similar to what @zerkms found).

This has proved more accurate for me.

    function _getBusinessDayOfMonth( $days ) {          $time = strtotime(date("m/1/Y 00:00")); //finding # of business days after 1st of the month         $i = 0; //start with zero         while ($i < $days) { //loop through until reached the amount of weekdays             $time = strtotime("+1 day", $time); //Increase day by 1             if (date("N", $time) < 6) { //test if M-F                 $i++; //Increase by 1             }         }         echo date("m/d/Y", $time);     }
