How can I convert days to a unixtimestamp?

Example if a user inputs 55 (=55 days) in a form, I wish to add 55 days, to the current time, and then store it in a unix timestamp.

Answer 1

Arithmetic with time():

$input = (int) $_POST['days'];
$timestamp = time() + $input * 86400;

or perhaps using strtotime():

$input = (int) $_POST['days'];
$timestamp = strtotime('+' . $input ' days');
