Stupid Question about date calculations ...

[bsamson]

Hey ALL!

 

I know how to add days to the current date,

 

<?php echo "15 Days from today is: ".date("m/d/Y", strtotime("+15 days"); ?>

 

How do I calculate 15 days from today when the user inputs the date (i.e. Not today)

 

example: 06/02/2008 + 15 days

 

Thanks in advance!

You might have to change this slightly depending on the format you're using for dates.

 

$date	= "06282008";	// Todays date

$month	= substr($date, 0, 2);
$day	= substr($date, 2, 2);
$year	= substr($date, 4, 4);

echo date("m/d/Y", mktime(1, 1, 1, $month, ($day+15), $year));

 

If this confuses you just read up on the mktime() PHP function and should be clear.

strtotime can do this as long as the existing date is in a format it understands. For your mm/dd/yyyy example -

 

<?php echo "15 Days from 06/02/2008 is: ".date("m/d/Y", strtotime("06/02/2008 + 15 days")); ?>
