PHP: Return all dates between two dates in an array [duplicate]
(26 answers)
Closed 4 years ago.
I want to get all the dates between two given specific dates which will be changing dynamically according to the user requirements.
This works fine for me :
$begin = new DateTime( '2018-07-01' );
$end = new DateTime( '2018-08-10' );
$end = $end->modify( '+1 day' );
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);
$dates = [];
foreach($daterange as $date){
array_push($dates,$date->format('Y-m-d'));
}
return $dates;
But this gives me NULL array when I insert dates dynamically. For example,
$begin = new DateTime($request->date1);
$end = new DateTime(today());
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);
$dates = [];
foreach($daterange as $date){
array_push($dates,$date->format('Y-m-d'));
}
return dates;
I have tried many inputs like storing today's date in a variable, changing it's format and then using that variable as an input. I tried changing date variable to string using (string) function and also I have used Carbon classes for dates, but somehow I am making mistake using DateTime, DateInterval and DatePeriod as I don't know the basics of them.
I need to get all the dates between two specific dates for charts in my admin panel.

Finally got the solution for this question. It worked by converting the dates to UNIX timestamp. Here's the code, how it worked:
$date_from = "2018-07-01";
$date_from = strtotime($date_from); // Convert date to a UNIX timestamp
// Specify the end date. This date can be any English textual format
$date_to = strtotime(today()); // Convert date to a UNIX timestamp
$dates = [];
// Loop from the start date to end date and output all dates inbetween
for ($i=$date_from; $i<=$date_to; $i+=86400) {
array_push($dates,date("Y-m-d", $i));
}
return $dates;
Here is the reference where I found this solution, hope this helps others too.
