Get all overlapsed dates from collection

[ShapesGraphicStudio]

Hello, I need to get a range of overlapping dates from a collection.

Maybe I missed something in the docs but I can not find something like:

$collection = new PeriodCollection(
    Period::make('2018-01-01', '2018-01-05'),
    Period::make('2018-01-10', '2018-01-15'),
    Period::make('2018-01-20', '2018-01-25'),
    Period::make('2018-01-30', '2018-01-31')
);

$gaps = $collection->gaps();

But getting: $overlaps = $collection->overlaps(); instead of gaps

Would that be possible ?

Best regards

Hi again,

I do not know if it's the best way to get there, but in case it can help somebody spare some time, here's what I did:

$periods = [];

foreach($items as $item) {
    if($item->model->time_limited) {
        $periods[$item->id] = Period::make($item->available_from,$item->available_to);
    }
}

$collection = new PeriodCollection(...$periods);
$boundaries = $collection->boundaries();

$overlaps = $boundaries->overlapAll(...$periods);

Seems to work fine. Best regards

EDIT Bummer, it worked fine till I got multiple overlaps, I then got: Call to a member function overlapSingle() on null In my case actually it's not a big issue as I do not want to proceed with more than one overlaps range, but it would be great to get overlaps as easily as we can get gaps.

My thought would be as you did, getting the boundaries of the collection and overlapping each individual period to that. Feel free to submit a PR to add eg. overlapAny to the PeriodCollection class.
