php - how to include time slot breaks using DateTime - php

Question

I want to create time slots with start, end time & also break start and end.
I have achieved to generate the time slots but without the break between 11:10 - 11:25
LIVE CODE EXAMPLE
Input variables
$duration = 35; // how much the is the duration of a time slot
$cleanup = 0; // don't mind this
$start = '09:00'; // start time
$end = '12:00'; // end time
$break_start = '11:10'; // break start
$break_end = '11:25'; // break end
function availableSlots($duration, $cleanup, $start, $end) {
$start = new DateTime($start);
$end = new DateTime($end);
$interval = new DateInterval("PT" . $duration . "M");
$cleanupInterval = new DateInterval("PT" . $cleanup . "M");
$periods = array();
for ($intStart = $start; $intStart < $end; $intStart->add($interval)->add($cleanupInterval)) {
$endPeriod = clone $intStart;
$endPeriod->add($interval);
if ($endPeriod > $end) {
break;
}
$periods[] = $intStart->format('H:i A') . ' - ' . $endPeriod->format('H:i A');
}
return $periods;
}
Function will generate this output:
09:00 AM - 09:35 AM
09:35 AM - 10:10 AM
10:10 AM - 10:45 AM
10:45 AM - 11:20 AM
11:20 AM - 11:55 AM
What i need to achieve is 11:10am till 11:25am break period to be excluded from the results.
$break_start = '11:10';
$break_end = '11:25';

Try this...
I have modified your function
function availableSlots($duration, $cleanup, $start, $end, $break_start, $break_end) {
$start = new DateTime($start);
$end = new DateTime($end);
$break_start = new DateTime($break_start);
$break_end = new DateTime($break_end);
$interval = new DateInterval("PT" . $duration . "M");
$cleanupInterval = new DateInterval("PT" . $cleanup . "M");
$periods = array();
for ($intStart = $start; $intStart < $end; $intStart->add($interval)->add($cleanupInterval)) {
$endPeriod = clone $intStart;
$endPeriod->add($interval);
if(strtotime($break_start->format('H:i A')) < strtotime($endPeriod->format('H:i A')) && strtotime($endPeriod->format('H:i A')) < strtotime($break_end->format('H:i A'))){
$endPeriod = $break_start;
$periods[] = $intStart->format('H:i A') . ' - ' . $endPeriod->format('H:i A');
$intStart = $break_end;
$endPeriod = $break_end;
$intStart->sub($interval);
}else{
$periods[] = $intStart->format('H:i A') . ' - ' . $endPeriod->format('H:i A');
}
}
return $periods;
}
$duration = 35; // how much the is the duration of a time slot
$cleanup = 0; // don't mind this
$start = '09:00'; // start time
$end = '12:00'; // end time
$break_start = '11:10'; // break start
$break_end = '11:25'; // break end
availableSlots($duration, $cleanup, $start, $end, $break_start, $break_end);
The Result will be:
Array
(
[0] => 09:00 AM - 09:35 AM
[1] => 09:35 AM - 10:10 AM
[2] => 10:10 AM - 10:45 AM
[3] => 10:45 AM - 11:10 AM
[4] => 11:25 AM - 12:00 PM
)
