PHP strtotime unexpected result

The below code echos out 20101111 instead of my expected result of 20101105.

I am running PHP 4.3.2.

Any Ideas why it is doing this?

<?

$date = date('Ymd',strtotime('+1 months',strtotime('20101001')));
echo date('Ymd',strtotime('next friday',strtotime($date)));
?>

on later php version it gives ok time..

you can try wit singular "month"

<?php

$date = date('Ymd',strtotime('+1 month',strtotime('20101001')));
echo date('Ymd',strtotime('next friday',strtotime($date)));
?>

ovi_mihai -  Changeing month the months did not work, the problem seems to be how strtotime handles next in php previous to version 4.4.

From PHP.net:
In PHP versions prior to 4.4.0, "next" is incorrectly computed as +2. A typical solution to this is to use "+1".

I need a work around for this know bug, besides upgrading php.

well, my understanding is previous works ok

so you could try the following
<?php

$date = date('Ymd',strtotime('+1 month',strtotime('20101001')));
echo date('Ymd',strtotime('previous friday',strtotime('next friday',strtotime($date))));
?>

try with "last" instead of "previous"
<?php

$date = date('Ymd',strtotime('+1 month',strtotime('20101001')));
echo date('Ymd',strtotime('previous friday',strtotime('next friday',strtotime($date))));
?>
