getting hours and day difference between two dates in codeigniter - codeigniter

Question

i am getting two dates as
$date1 = 2020-07-16 03:50:32
$date2 = 2017-01-25 09:43:53
i want to get the difference between thes two dates.
THe difference count hours until 24 hours and then days plus hours.
eg. 2 days and 5 hours.
THe code i tried is this
$createddate = date("d-m-Y H:i:s", strtotime($application['created_at']));
$approvedisapprovedate = date("d-m-Y H:i:s", strtotime($application['approved_at']));
$created = strtotime($createddate);
$approvedisapprove = strtotime($approvedisapprovedate);
$diff = $approvedisapprove - $created;
$days = floor($diff / (60 * 60 * 24));
$hours = round(($diff - $days * 60 * 60 * 24) / (60 * 60));
but it won't work.anybody suggest a solution.

Answer 1

You can use carbon for this. Carbon can make it simple to manipulate dates very efficiently not for only this task but many other related date.
Install carbon
{
"require": {
"nesbot/carbon": "^1.22"
}
}
Usage
$date->diffForHumans();
OR
$date->diffInDays();
In your case, you can try below code -
$createddate = Carbon::parse($application['created_at']);
$approvedisapprovedate = Carbon::parse($application['approved_at']);
//here is carbon magic
$createddate->diffInDays($approvedisapprovedate); //This will give you diff in number of days.
$createddate->diffForHumans($approvedisapprovedate); //This will give you diff which is readable by human. ex- 1 day 2 hours
You can refer Carbon.
Hope this will help for you.

I propose you the DateInterval::format function of php
like this:
$createddate = new DateTime('12-07-2020 12:10:01');
$approvedisapprovedate = new DateTime('16-07-2020 13:15:40');
$interval = $approvedisapprovedate->diff($createddate);
echo $interval->format('%a days %h hours %i minutes')."\n";
It goes back to this:
4 days 1 hours 5 minutes
I don't know the format of the date $application['created_at'] and $application['approved_at'] but I just put it there:
$createddate = new DateTime($application['created_at']);
$approvedisapprovedate = new DateTime($application['approved_at']);
$interval = $approvedisapprovedate->diff($createddate);
echo $interval->format('%a days %h hours %i minutes')."\n";
