Requirement: PHP 5 >= 5.2.0

You should make use of the DateTime and DateInterval classes in Php, and things will turn to be very easy and readable.

Example: Lets get the previous day.

// always make sure to have set your default timezone
date_default_timezone_set('Europe/Berlin');

// create DateTime instance, holding the current datetime
$datetime = new DateTime();

// create one day interval
$interval = new DateInterval('P1D');

// modify the DateTime instance
$datetime->sub($interval);

// display the result, or print_r($datetime); for more insight 
echo $datetime->format('Y-m-d');


/** 
* TIP:
* if you dont want to change the default timezone, use
* use the DateTimeZone class instead.
*
* $myTimezone = new DateTimeZone('Europe/Berlin');
* $datetime->setTimezone($myTimezone); 
*
* or just include it inside the constructor 
* in this form new DateTime("now",   $myTimezone);
*/
