How to find next date removing weekend and public holiday starting from today in PHP

Ok, so here is a snippets of finding out the next business or working day excluding public holiday that i used in a project. Its pretty neat, but holidays date changes every year and each country holiday is different from each other. Therefore, the holidays are being placed in an array instead. Without further ado, here's the snippets.

// get today date
$tmpDate = date('Y-m-d');
// all the holidays
$holidays = array('2015-01-01', '2015-01-02', '2015-02-04', '2015-02-18', '2015-02-19', '2015-02-20', '2015-02-21', '2015-02-22', '2015-02-23', '2015-02-27',
    '2015-02-28', '2015-03-05', '2015-03-08', '2015-03-12', '2015-03-20', '2015-03-21', '2015-03-29', '2015-04-03', '2015-04-04', '2015-04-05',
    '2015-04-06', '2015-04-07', '2015-05-01', '2015-05-03', '2015-05-04', '2015-05-10', '2015-05-11', '2015-05-25', '2015-06-03', '2015-06-19',
    '2015-06-20', '2015-06-21', '2015-06-28', '2015-08-08', '2015-08-20', '2015-08-28', '2015-09-03', '2015-09-23', '2015-09-26', '2015-09-27',
    '2015-09-28', '2015-10-09', '2015-10-10', '2015-10-21', '2015-10-25', '2015-11-12', '2015-11-26', '2015-12-22', '2015-12-25');
// 1 day
$i = 1;
// for the next business day from today
$nextBusinessDay = date('Y-m-d', strtotime($tmpDate.
    ' +'.$i.
    ' Weekday'));
// check whether the date of the business day is in public holiday
while (in_array($nextBusinessDay, $holidays)) {
    $i++;
    // move the business date forward since its a public holiday
    $nextBusinessDay = date('Y-m-d', strtotime($tmpDate.
        ' +'.$i.
        ' Weekday'));
}

Now, the code above will find the next working day. How about telling me how to find 10 days after the working day? Pretty much the same just repeat the same logic and place it below it,
