How many days until XXX date?

Question

Given a certain date, whats the easiest way to determine how many days until that date (in PHP)? I am trying to build a count-down widget, Thanks!

Answer 1

From here:

<?php 
$cdate = mktime(0, 0, 0, 12, 31, 2009, 0);
$today = time();
$difference = $cdate - $today;
if ($difference < 0) { $difference = 0; }
echo "There are ". floor($difference/60/60/24)." days remaining";
?>

Answer 2

Don't treat dates as integers. Use your database, which has good support for dealing with calendars/time.

select datediff("2009-11-12", now())

Answer 3

PHP 5.3 has introduced the DateTime class that implements a 'diff' function. See http://www.php.net/manual/en/datetime.diff.php
