Description:
------------
strtotime() of PHP 5.3.0alpha3 returns inconsistent and incompatible result with 'first day' 'last day' 'previous week' 'next week'.

PHP 5.2.8 produces consistent result, and meaning of 'first' 'next' 'last' 'previous' is clear for me.

The behaviour of PHP 5.3.0's strtotime() is sometimes natural, but it lacks consistency and documentation, I think.

Reproduce code:
---------------
<?php

var_dump(date("Y-m-d", strtotime("20081224 first day")));
var_dump(date("Y-m-d", strtotime("20081224 next day")));

var_dump(date("Y-m-d", strtotime("20081224 last day")));
var_dump(date("Y-m-d", strtotime("20081224 previous day")));

var_dump(date("Y-m-d", strtotime("20081224 first week")));
var_dump(date("Y-m-d", strtotime("20081224 next week")));

var_dump(date("Y-m-d", strtotime("20081224 last week")));
var_dump(date("Y-m-d", strtotime("20081224 previous week")));

Expected result:
----------------
string(10) "2008-12-25"
string(10) "2008-12-25"
string(10) "2008-12-23"
string(10) "2008-12-23"
string(10) "2008-12-31"
string(10) "2008-12-31"
string(10) "2008-12-17"
string(10) "2008-12-17"

Actual result:
--------------
string(10) "2008-12-01"
string(10) "2008-12-25"
string(10) "2008-12-31"
string(10) "2008-12-23"
string(10) "1970-01-01"
string(10) "2008-12-29"
string(10) "2008-12-15"
string(10) "2008-12-15"

5.3 does the proper behavior.

Duplicate of #42489 — also, the PHP 5.3 behaviour is correct. Fixing this in 5.2 would require merging too much code that can break other things, so I don't think it's wise to merge.
