How to get time slots for a specific date - php

Question

Hope all are doing well. I need to print an array as time slots.
Assume that there are 2 orders for 2021.11.15 on 11:30am to 12:00pm and 2:00pm to 4:15pm.
My order needs 1h 30m to complete. Therefore time slots should be in between 8:00am and 6:00pm skipping those times for already exist orders.
My expected results should be:
array:2 [
0 => array:2 [
"start" => "08:00:00"
"end" => "9:30:00"
]
1 => array:2 [
"start" => "09:30:00"
"end" => "11:00:00"
]
2 => array:2 [
"start" => "12:00:00"
"end" => "13:30:00"
]
3 => array:2 [
"start" => "16:15:00"
"end" => "17:45:00"
]
]
Following line is used to get exist orders object with their start and end times.
$existOrders = $this->orderHasPropartnerService->getOrderExistForDateProPartner($proPartnerDefaultLocation->id, $selectedDateRecord->date);
Then I just looped it.
if ($existOrders->count() > 0) {
$dateStartTime = $selectedDateRecord->time_from;
$x = 0;
$firstEndingTime = Carbon::parse($dateStartTime)->addMinutes($totalTimeToOrder)->format('H:i:s');
foreach ($existOrders as $key1 => $existOrder1) {
if ($existOrder1->order->time_slot_from < $firstEndingTime && $existOrder1->order->time_slot_to >= $firstEndingTime) {
$timeCheckArray[$x]['start'] = $existOrder1->order->time_slot_to;
$timeCheckArray[$x]['end'] = Carbon::parse($existOrder1->order->time_slot_to)->addMinutes($totalTimeToOrder)->format('H:i:s');
} else {
$timeSlotArray[$x]['start'] = $dateStartTime;
$timeSlotArray[$x]['end'] = $firstEndingTime;
$timeCheckArray[$x]['start'] = $firstEndingTime;
$timeCheckArray[$x]['end'] = Carbon::parse($firstEndingTime)->addMinutes($totalTimeToOrder)->format('H:i:s');
}
if (isset($existOrders[$key1+1])) {
if ($existOrders[$key1+1]->order->time_slot_from < $timeCheckArray[$x]['end'] && $existOrders[$key1+1]->order->time_slot_to >= $timeCheckArray[$x]['end']) {
} else {
$timeSlotArray[$x+1]['start'] = $timeCheckArray[$x]['start'];
$timeSlotArray[$x+1]['end'] = $timeCheckArray[$x]['end'];
}
}
}
}
As for the above example $dateStartTime will be 8:00am. Value of $totalTimeToOrder will be 1h 30m.
When I try to print $timeSlotArray it'll result as follows:
array:2 [
0 => array:2 [
"start" => "08:00:00"
"end" => "09:30:00"
]
1 => array:2 [
"start" => "08:00:00"
"end" => "09:30:00"
]
]
It is really appreciated if someone point me out where I did mistakes in this logic. Thank you so much guys for your valuable time for a problem of mine.

The best approach would be to run a for loop to check that the New order does not fall between the booked times .
Try something similar to this by converting it to a PHP Date object
$NewOrder= "4:59 pm";
$start= "5:42 am";
$end= "6:26 pm";
$date1 = DateTime::createFromFormat('h:i a', $NewOrder);
$date2 = DateTime::createFromFormat('h:i a', $start);
$date3 = DateTime::createFromFormat('h:i a', $end);
if ($date1 > $date2 && $date1 < $date3)
{
echo 'Not safe to add it ';
}
