How to calculate the difference between two dates using PHP?

Solution for : How to calculate the difference between two dates using PHP?

I suggest to use DateTime and DateInterval objects.

?

1 2 3 4 5 6 7

$date1 = new DateTime("2007-03-24"); $date2 = new DateTime("2009-06-26"); $interval = $date1->diff($date2); echo "difference " . $interval->y . " years, " . $interval->m." months, ".$interval->d." days ";   // shows the total amount of days (not divided into years, months and days like above) echo "difference " . $interval->days . " days ";

From the manual:

As of PHP 5.2.2, DateTime objects can be compared using comparison operators.

1 2 3 4 5 6

$date1 = new DateTime("now"); $date2 = new DateTime("tomorrow");   var_dump($date1 == $date2); // bool(false) var_dump($date1 < $date2);  // bool(true) var_dump($date1 > $date2);  // bool(false)
