PHP Question

Day difference without weekends

I want to count the total day difference from user input

For example when the user inputs

start_date = 2012-09-06
end-date = 2012-09-11

For now I am using this code to find the diffeence

$count = abs(strtotime($start_date) - strtotime($end_date));
$day = $count+86400;
$total = floor($day/(60*60*24));

The result of total will be 6. But the problem is that I dont want to include the days at weekend (Saturday and Sunday)

2012-09-08 Saturday
2012-09-09 Sunday

So the result will be 4


I have a table that contains date,the table name is holiday date

for example the table contains

So, the total day will be 3, because it didn't count the holiday date

how do I do that to equate the date from input to date in table?

Very easy with my favourites: DateTime, DateInterval and DatePeriod

$start = new DateTime('2012-09-06');
$end = new DateTime('2012-09-11');
// otherwise the  end date is excluded (bug?)
$end->modify('+1 day');

$interval = $end->diff($start);

// total days
$days = $interval->days;

// create an iterateable period of date (P1D equates to 1 day)
$period = new DatePeriod($start, new DateInterval('P1D'), $end);

// best stored as array, so you can add more than one
$holidays = array('2012-09-07');

foreach($period as $dt) {
    $curr = $dt->format('D');

    // for the updated question
    if (in_array($dt->format('Y-m-d'), $holidays)) {

    // substract if Saturday or Sunday
    if ($curr == 'Sat' || $curr == 'Sun') {

echo $days; // 4
