Bug description:strtotime() unexpectedly changed from 5.2.13 to 5.3.2 breaking
alot of scripts
Description:
------------
In version 5.2.13 the following code:
<?php
echo ($now = strtotime('+1 day')) . ' - ' . date('d-m-Y H.i.s', $now) .
"\n";
echo ($last = strtotime('last week', $now)) . ' - ' . date('d-m-Y H.i.s',
$last) . "\n";
echo ($next = strtotime('+1 week', $last)) . ' - ' . date('d-m-Y H.i.s',
$next) . "\n";
?>
Gives the following result:
1277283067 - 23-06-2010 09.51.07
1276678267 - 16-06-2010 09.51.07
1277283067 - 23-06-2010 09.51.07
That is, first line is current time.
Second time is "last week", otherwise known as "-1 week".
Third time is "+1 week", which reverses the change that the "-1 week" did.
However, this changed in 5.3.2 and it now gives the following result:
1277281904 - 23-06-2010 09.31.44
1276504304 - 14-06-2010 09.31.44
1277109104 - 21-06-2010 09.31.44
So it appears "last week" is no longer the equivalent of "-1 week".
Is this a deliberate change or something that was broken in 5.3.2?
I have been unable to test other versions and can only give you the
difference from 5.2.13 and 5.3.2.
Thanks.
Test script:
---------------
<?php
echo ($now = strtotime('+1 day')) . ' - ' . date('d-m-Y H.i.s', $now) .
"\n";
echo ($last = strtotime('last week', $now)) . ' - ' . date('d-m-Y H.i.s',
$last) . "\n";
echo ($next = strtotime('+1 week', $last)) . ' - ' . date('d-m-Y H.i.s',
$next) . "\n";
?>
Expected result:
----------------
1277283067 - 23-06-2010 09.51.07
1276678267 - 16-06-2010 09.51.07
1277283067 - 23-06-2010 09.51.07
Actual result:
--------------
1277281904 - 23-06-2010 09.31.44
1276504304 - 14-06-2010 09.31.44
1277109104 - 21-06-2010 09.31.44
