Share PHP to calculate the number of days between two dates code, _php tutorial

Share PHP to calculate the number of days between two dates code,

This example describes how PHP calculates the two-day difference between days. Share to everyone for your reference. The implementation method is as follows:

<?php$date1 = Date (' y-m-d '), $date 2 = "2015-12-04", $diff = ABS (Strtotime ($date 2)-Strtotime ($date 1)); $years = Floor ($ Diff/(365*60*60*24)); $months = Floor (($diff-$years * 365*60*60*24)/(30*60*60*24)), $days = Floor (($diff-$years * 36 5*60*60*24-$months *30*60*60*24)/(60*60*24));p rintf ("%d years,%d months,%d days\n", $years, $months, $days);--------- -----------------------------------------------or$date1 = new DateTime ("2007-03-24"), $date 2 = new DateTime (" 2009-06-26 "), $interval = $date 1->diff ($date 2); echo" Difference ". $interval->y. "Years,". $interval->m. "Months,". $interval->d. "Days"; Shows the total amount's (not divided to years, months and days like above) echo "difference". $interval->days.  "Days";--------------------------------------------------------or/** * Calculate differences between, dates with Precise semantics.
