Count days between two dates in yii2 - php

Question

Today I am counting days between two dates in yii2. One date is on column of database. Database column is due_date. The other date is current date.
Here is the code for what I done so far in yii2 :
$abc=Yii::$app->db->createCommand('select * from lib_chekout where patron_id=:patron_id AND is_checkedin=0')
->bindValue(':patron_id',$patron_id)
->queryAll();
$datetime1 = $abc[0]['due_date'];
$datetime2 = date("Y-m-d H:i:s");
$interval = $datetime1->diff($datetime2);
print_r($interval);
exit;
My due_date is no $abc array . Now how can I count the dates ?
For reference due_date has date 2011-08-13 00:00:00. And today date is 2016-12-13.
How can I do it ?

Answer 1

as #kashif said you can use date_diff function. first you need to convert you date to DateTimeInterface then pass it to date_diff.
//PARA: Date Should In YYYY-MM-DD Format
//RESULT FORMAT:
// '%y Year %m Month %d Day %h Hours %i Minute %s Seconds' => 1 Year 3 Month 14 Day 11 Hours 49 Minute 36 Seconds
// '%y Year %m Month %d Day' => 1 Year 3 Month 14 Days
// '%m Month %d Day' => 3 Month 14 Day
// '%d Day %h Hours' => 14 Day 11 Hours
// '%d Day' => 14 Days
// '%h Hours %i Minute %s Seconds' => 11 Hours 49 Minute 36 Seconds
// '%i Minute %s Seconds' => 49 Minute 36 Seconds
// '%h Hours => 11 Hours
// '%a Days => 468 Days
//////////////////////////////////////////////////////////////////////
function dateDifference($date_1 , $date_2 , $differenceFormat = '%a' )
{
$datetime1 = date_create($date_1);
$datetime2 = date_create($date_2);
$interval = date_diff($datetime1, $datetime2);
return $interval->format($differenceFormat);
}
from here

Answer 2

DateTime::diff -- DateTimeImmutable::diff -- DateTimeInterface::diff -- date_diff — Returns the difference between two DateTime objects
You must convert your date string into datetime object
$abc = Yii::$app->db->createCommand('select * from lib_chekout where patron_id=:patron_id AND is_checkedin=0')
->bindValue(':patron_id',$patron_id)
->queryAll();
$datetime1 = new Datetime($abc[0]['due_date']);
$datetime2 = new Datetime(date("Y-m-d H:i:s"));
$interval = $datetime1->diff($datetime2)->days;
print_r($interval);
exit;

Try this way.
$datetime1 and $datetime2 should be DateTime object.
$datetime1 = new DateTime('2011-08-13 00:00:00');
//$datetime1 = new DateTime($abc[0]['due_date']);
$datetime2 = new DateTIme('Now');
$interval = $datetime1->diff($datetime2);
print_r($interval->format('%R%a'));
