如何检查php中两个日期之间是否有周末？

I want to check if there is any sat or sun between two dates in php.

$fromDate = '03/21/2016';
$toDate = '03/28/2016';

I've tried other solution asked here but they didn't worked well. I want it in laravel 5.2 so if there is any easy way to handle this please guide me. thanks!

Update i also want to get if there is weekday(mon-fri) between two dates. i need it because user can select sat and Sunday only so in this condition I've to hide weekday option from him. So what I need is a method which tells me if start and end date has weekend or weekdays or both in it.

You can use date("N") to get current day of week and add the difference of days between your dates.. If this is bigger or equal to 6 than it's a weekend between or one date is in weekend.

//Get current day of week. For example Friday = 5
$day_of_week = date("N", strtotime($fromDate));

$days = $day_of_week + (strtotime($toDate) - strtotime($fromDate)) / (60*60*24)
//strtotime(...) - convert a string date to unixtimestamp in seconds.
//The difference between strtotime($toDate) - strtotime($fromDate) is the number of seconds between this 2 dates. 
//We divide by (60*60*24) to know the number of days between this 2 dates (60 - seconds, 60 - minutes, 24 - hours)
//After that add the number of days between this 2 dates to day of week. So if first date is friday and days between this 2 dates is: 3 the sum will be 5+3 = 8 and it's bigger than 6 so we know it's a weekend between.



if($days >= 6){
  //we have a weekend. Because day of week of first date + how many days between this 2 dates are greater or equal to 6 (6=Saturday)
} else {
  //we don't have a weekend
}

try

<?php
    $is_weekend = 0;
    $fromDate = strtotime('2016-03-21');
    $toDate = strtotime('2016-03-28');
    while (date("Y-m-d", $fromDate) != date("Y-m-d", $toDate)) {
        $day = date("w", $fromDate);
        if ($day == 0 || $day == 6) {
            $is_weekend = 1;
        }
        $fromDate = strtotime(date("Y-m-d", $fromDate) . "+1 day");
    }
    echo $is_weekend;

hoe it helps :)
