How to get 7(X) days back date from current date?

PHP is very strong server side programming language which simplifies lots of small small tasks like converting date formats etc.

I was working on some task, where I was suppose to get 7 days back date from current date. Actually the task is very simple, I am sharing the code here. Have a look at it and let me know if any one can find better way than this.


$format = 'YmdhIS'; // YOU CAN USE ANY FORMAT WHICH YOU WANT

$date = date ( $format );

// - 7 days from today
$prevDate = date ( $format, strtotime ( '-7 day' . $date ) );

Note: If you want to get yesterdays date then simply do -1 instead of -7.
