datetime difference in php

//get Date diff as intervals 
$d1 = new DateTime("2018-01-10 00:00:00");
$d2 = new DateTime("2019-05-18 01:23:45");
$interval = $d1->diff($d2);
$diffInSeconds = $interval->s; //45
$diffInMinutes = $interval->i; //23
$diffInHours   = $interval->h; //8
$diffInDays    = $interval->d; //21
$diffInMonths  = $interval->m; //4
$diffInYears   = $interval->y; //1

//or get Date difference as total difference
$d1 = strtotime("2018-01-10 00:00:00");
$d2 = strtotime("2019-05-18 01:23:45");
$totalSecondsDiff = abs($d1-$d2); //42600225
$totalMinutesDiff = $totalSecondsDiff/60; //710003.75
$totalHoursDiff   = $totalSecondsDiff/60/60;//11833.39
$totalDaysDiff    = $totalSecondsDiff/60/60/24; //493.05
$totalMonthsDiff  = $totalSecondsDiff/60/60/24/30; //16.43
$totalYearsDiff   = $totalSecondsDiff/60/60/24/365; //1.35

difference of two dates in seconds php

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

php calculate time difference in percentage

First, make those minutes into seconds:

4 min 35 sec = 275 seconds

11 min = 660 seconds

Your percentage of remaining time will be (275 / 660) * 100. The percentage of time left would be ((660 - 275) / 660) * 100. Of course, that's all in seconds. Don't know how you are receiving that time in php, but it might look like:

$maxTime = 660;
$timeTaken = 275;

$percentage = ($timeTaken / $maxTime) * 100;

// To get percentage of time left
$percentLeft = (($maxTime - $timeTaken) / $maxTime) * 100;
