How to set a date of n number of days ago in php

Question

I have a php variable:

$datevar = date("Y-m-d");

Which shows me the CURRENT date in the specified format.

What I want is the date from 7 days ago for CURRENT date in that format. I have tried:

$datevar = $datevar - 7; 

and

$datevar = date("Y-m-d") - 7 ;

But they both cause an error.

Answer 1

I refer to this solution: https://stackoverflow.com/a/3727821/7454754

So in your example this would be something like

<?php
  $today = date("Y-m-d");
  $newDate = date("Y-m-d", strtotime($today . " - 7 days"));
?>

Answer 2

Try the code below, that should work:

$date = date("Y-m-d");// current date 
$date = strtotime(date("Y-m-d", strtotime($date)) . " -1 week");

Answer 3

You can do it like this. Here we are using DateTime and DateInterval

Try this code snippet here

<?php

$datevar = date("Y-m-d");//your date

$dateTimeObj=new DateTime($datevar);
$dateTimeObj->sub(new DateInterval("P7D"));//subtracting 7 days
echo $dateTimeObj->format("Y-m-d");
