PHP DatePeriod not working as expected
Question
I am creating a booking system where user A can insert personal available times in the database. I am storing these as timestamp in MySql database as start_time and end_time . If user selects times between 00:00:00 to lets say 14:00:00 my code works perfectly. I generate a 30 minutes interval and store the times. Now when user selects lets say a whole day 00:00:00 to 00:00:00 or midnight then I get the correct DatePeriod , but when I split this into 30 minute intervals it shows the last time as current date and 00:00:00 but what I would need is the end date to be next days 00:00:00 .
This is what I have at the moment:
//get variables
$start_date = Input::get('start');
$end_date = Input::get('end');
$startDate = new DateTime($start_date);
$endDate = new DateTime($end_date);
$interval = new DateInterval('PT30M'); //interval of 30 minutes
$available_times_date_range = new DatePeriod($startDate, $interval ,$endDate);
//store the times in array
foreach($available_times_date_range as $available_date){
$dates_and_times[] = [
'start_time' => $available_date->format("Y-m-d")." ".$available_date->format("H:i:s"),
'end_time' => $available_date->format("Y-m-d")." ".$available_date->add($interval)->format("H:i:s")
];
}
//insert to database
foreach ($dates_and_times as $date_and_time) {
$test[] = $date_and_time['end_time'];
$start_time = $date_and_time['start_time'];
$end_time = $date_and_time['end_time'];
//insert
// Nanny_availability::addAvailability($start_time, $end_time);
}
When I select from midnight to midnight I get this json returned from $available_times_date_range
{
"start":{
"date":"2017-11-30 00:00:00.000000",
"timezone_type":3,
"timezone":"Europe\/Helsinki"
},
"current":{
"date":"2017-12-01 00:00:00.000000",
"timezone_type":3,
"timezone":"Europe\/Helsinki"
},
"end":{
"date":"2017-12-01 00:00:00.000000",
"timezone_type":3,
"timezone":"Europe\/Helsinki"
},
"interval":{
"y":0,
"m":0,
"d":0,
"h":0,
"i":30,
"s":0,
"weekday":0,
"weekday_behavior":0,
"first_last_day_of":0,
"invert":0,
"days":false,
"special_type":0,
"special_amount":0,
"have_weekday_relative":0,
"have_special_relative":0
},
"recurrences":1,
"include_start_date":true
}
but in my foreach($available_times_date_range as $available_date) I get the response like this:
[
{
"start_time":"2017-11-30 00:00:00",
"end_time":"2017-11-30 00:30:00"
},
//all the other objects
{
"start_time":"2017-11-30 23:30:00",
"end_time":"2017-11-30 00:00:00"
}
]
So the last end_time should be 2017-12-01 00:00:00 . How can I achieve that?

The problem arises with your modification of $available_date for the end time, but not the end date. Add the interval before adding the formatted date to your array.
foreach($available_times_date_range as $available_date){
$dates_and_times[] = [
'start_time' => $available_date->format("Y-m-d")." ".$available_date->format("H:i:s"),
'end_time' => $available_date->add($interval)->format("Y-m-d")." ".$available_date->format("H:i:s")
];
}
Personally, I'd prefer to set end date/time slightly differently
foreach($available_times_date_range as $available_date){
$endTime = (clone $available_date)->add($interval);
$dates_and_times[] = [
'start_time' => $available_date->format("Y-m-d H:i:s"),
'end_time' => $endTime->format("Y-m-d H:i:s"),
];
}
(note that cloning like this requires PHP7)

Hi it is pretty simple
For calculating end date u can do like this
'end_time' => $available_date->add($interval)->format("Y-m-d H:i:s")
in your case your printing old date and adding interval later, that was causing the problem
following update code should worl
//get variables
$start_date = '2017-11-30 00:00:00.000000';
$end_date = '2017-12-01 00:00:00.000000';
$startDate = new DateTime($start_date);
$endDate = new DateTime($end_date);
$interval = new DateInterval('PT30M'); //interval of 30 minutes
$available_times_date_range = new DatePeriod($startDate, $interval ,$endDate);
//store the times in array
foreach($available_times_date_range as $available_date){
$dates_and_times[] = [
'start_time' => $available_date->format("Y-m-d")." ".$available_date->format("H:i:s"),
'end_time' => $available_date->add($interval)->format("Y-m-d H:i:s")
];
}
print_r($dates_and_times);
