Logic for Time Slot Availability
Hi Experts;
I need to figure out 90min free time slots, for each day in question, but I can't seem to get it quite right.
So far I have the following 3 arrays, which show correct data below ($days, $events, $daily_slots):
$days - are the days in question:
$events - are events already in my calendar
$daily_slots - these are all possible 90min time slot that any work days can have, between 9 and 4 in 30 minutes increments
As mentioned I believe that all 3 above are correct. That said, I need to get all free 90 minutes slots based on this.
I have tried the following
...But I am not gettign what I need, and as you can see I have tried a few things. My latest output of $available is
I had thought that the following should work: if slot ends before or at event start OR if slot starts after or at event end, then slot is available, but it is not happening.

I have tried the following
//Loop through each day and get available slots
$available = array();
$available_counter = -1;
foreach($days as $day):
$available_counter++;
$available[$available_counter]['date'] = date('D. M. d', strtotime($day));
$slots = array();
foreach($daily_slots as $day_slot):
foreach($events as $event):
if (strtotime($event['date']) == strtotime($day)){
$slot_form = date($day . strtotime($day_slot['from']));
$slot_to = date($day . strtotime($day_slot['to']));
if (($day_slot['to'] <= $event['start']) ||
($day . $day_slot['from'] >= $event['end'])){ //Day Slot is available
// if (strtotime($day . $day_slot['to']) <= (strtotime($event['start'])) ||
// (strtotime($day . $day_slot['from']) >= (strtotime($event['end'])))){ //Day Slot is available
$slots[] = $day_slot;
echo 'available';
} else { echo 'not available'; }
}
endforeach; //event
endforeach; //Daily Slots
$available[$available_counter]['slots'] = $slots;
endforeach; //Days
...But I am not gettign what I need, and as you can see I have tried a few things. My latest output of $available is

=========END=========I had thought that the following should work: if slot ends before or at event start OR if slot starts after or at event end, then slot is available, but it is not happening.
