How to quickly sum days of events in a time range?

Description of the Issue:

I want to quickly sum days of events in a time range (i.e month of October 2018). I've tried to use the numberofDays method but I don't actually know how to use it :

• What is $days?
• What format of $start and $end should I use?

Without knowing the answers I've tried it anyway, getting this: Uncaught Error: Call to protected method ICal\ICal::numberofDays() from context

Here's the ICS file URL (it can't be used for initURL, so you need to download it first) : https://www.airbnb.com/calendar/ical/2051868.ics?s=0624fe394b3084d9f07ae453082c76e9

Code that I've tested:

$events = $ical->eventsFromRange('2018-12-01 00:00:00', '2018-12-31 23:59:59');
                foreach ($events as $event) :
                    $day = $ical->numberofDays($event->$dtstart_array[2],$event->$dtend_array[2]);
                    $days += $day;
                endforeach
var_dump($days);

I am not sure you can have tested the code provided.

• numberofDays() should be numberOfDays()
  • Although as you have discovered it is a protected method and for internal use only
• $event->$dtstart_array[2] should be $event->dtstart_array[2]
• $event->$dtend_array[2] should be $event->dtend_array[2]
• There is a semicolon missing after the endforeach
• $days has not been defined

As you have Carbon at your disposal I would do the following.

<?php

use Carbon\Carbon;

// Load iCal...

$events = $ical->eventsFromRange('2018-12-01 00:00:00', '2018-12-31 23:59:59');
$days   = 0;

foreach ($events as $event) :
    $end   = Carbon::createFromTimestamp($event->dtend_array[2]);
    $start = Carbon::createFromTimestamp($event->dtstart_array[2]);
    $days += $end->diffInDays($start);
endforeach;

var_dump($days);

• You have also not said what you expect the output to be.
• I got 8 days so hopefully that is what you were looking for.
