Answer 1

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 don't want to change the default timezone, 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);
