Finding the number of days between two dates

Question

How to find number of days between two dates using PHP?

Answer 1

$now = time(); // or your date as well $your_date = strtotime("2010-01-31"); $datediff = $now - $your_date;  echo round($datediff / (60 * 60 * 24)); 

Answer 2

If you're using PHP 5.3 >, this is by far the most accurate way of calculating the absolute difference:

$earlier = new DateTime("2010-07-06"); $later = new DateTime("2010-07-09");  $abs_diff = $later->diff($earlier)->format("%a"); //3 

If you need a relative (signed) number of days, use this instead:

$earlier = new DateTime("2010-07-06"); $later = new DateTime("2010-07-09");  $pos_diff = $earlier->diff($later)->format("%r%a"); //3 $neg_diff = $later->diff($earlier)->format("%r%a"); //-3
