get yesterday's date by selected date on Calender in php

Question

Selecting a date on the Calender which format is:

YYYY-MM-DD

for instance:

2011-11-01

Then I want to display the yesterday's date (i.e 2011-09-30) after clicking "one day before" button.

Is there anyone who know how to do it in pure php?

Thanks in advance.

Well it would require a page load (if you are not using any javascript ajax functionality)

To get yesterday's date you do:

$date = date('Y-m-d', strtotime('-1 day'));
