PHP Date Function Seven days previous

Question

I am trying to use PHP's Date Function to get the date of 7 days earlier in YYYY-MM-DD format.

date('Y-m-d'); 

when i try

date('Y-m-d-7'); 

i get an error

Answer 1

Use the strtotime method provided by PHP.

date('Y-m-d', strtotime('-7 days'))

Thanks to @lonesomeday for pointing out my mistake in the comments ;)

Answer 2

With this, as with all PHP date stuff, it's nicer to use the DateTime class.

$date = new DateTime('7 days ago'); echo $date->format('Y-m-d');
