difference between two dates in months php code example
Example 1: php calculate date difference
$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;
$diffInMinutes = $interval->i;
$diffInHours = $interval->h;
$diffInDays = $interval->d;
$diffInMonths = $interval->m;
$diffInYears = $interval->y;
$d1 = strtotime("2018-01-10 00:00:00");
$d2 = strtotime("2019-05-18 01:23:45");
$totalSecondsDiff = abs($d1-$d2);
$totalMinutesDiff = $totalSecondsDiff/60;
$totalHoursDiff = $totalSecondsDiff/60/60;
$totalDaysDiff = $totalSecondsDiff/60/60/24;
$totalMonthsDiff = $totalSecondsDiff/60/60/24/30;
$totalYearsDiff = $totalSecondsDiff/60/60/24/365;
Example 2: Calculate the Difference Between Two Dates Using PHP
$firstDate = "2019-01-01";
$secondDate = "2020-03-04";
$dateDifference = abs(strtotime($secondDate) - strtotime($firstDate));
$years = floor($dateDifference / (365 * 60 * 60 * 24));
$months = floor(($dateDifference - $years * 365 * 60 * 60 * 24) / (30 * 60 * 60 * 24));
$days = floor(($dateDifference - $years * 365 * 60 * 60 * 24 - $months * 30 * 60 * 60 *24) / (60 * 60 * 24));
echo $years." year, ".$months." months and ".$days." days";
