PHP - strtotime using phrase "first day of last week" not correct

Question

Using the code:

$from_date = date("Y-m-d 00:00:00", strtotime("first day of last week"));

returns: "2020-10-01 00:00:00", when I expect it to return "2020-10-25 00:00:00".

Why is it returning the first day of the month?

How can I get the first day of last week (and also the last day of last week)?

Answer 1

try this:

<?php

$from_date = date("Y-m-d 00:00:00", strtotime("last week last sunday"));

echo $from_date;
//returns 2020-10-25 00:00:00;

I've tested the dates on 7.1.0 version
