Calculate business days

Question

I need a method for adding \"business days\" in PHP. For example, Friday 12/5 + 3 business days = Wednesday 12/10.

At a minimum I need the code to understand weekend

Answer 1

For holidays, make an array of days in some format that date() can produce. Example:

// I know, these aren't holidays
$holidays = array(
    'Jan 2',
    'Feb 3',
    'Mar 5',
    'Apr 7',
    // ...
);

Then use the in_array() and date() functions to check if the timestamp represents a holiday:

$day_of_year = date('M j', $timestamp);
$is_holiday = in_array($day_of_year, $holidays);
