 Bug Type:         Date/time related
 Operating System: Linux
 PHP Version:      4.3.4
 New Comment:

it's easy:

"monday" or "first monday" means the first available monday from the
current time.

"next monday" or "second monday" means the second available monday from
the current time.



And bickering over PHP being non standard is not helping anybody. I did
do some research though with the unix "date" command, and it seems that
it is indeed behaving like you should say so. So I have to agree that
it's a bug somewhere.



Though the GNU manual definitely states that "next" is "2".

OK, I am stupid then... The explanation did not help clarify why this
is correct behavior, given, on Saturday the 28th of Feb, 2004, "next
Monday" (in the GNU/PHP world) is March 8th.  Bummer, that means that
if GNU/PHP is cutting my paycheck I'd be a week short.  Maybe I should
go back to perl, PHP is too 'occasionally' different but still totally
correct. Well, as long as you're not running it in production it won't
ever really matter.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

On the system you say it \"works\" is PHP 4.1.2, but actually it was a
bug in that version. strtotime() follows the GNU semantics (as you can
read on php.net/strtotime) and they say:



(from:
http://www.gnu.org/software/tar/manual/html_chapter/tar_7.html#SEC103)

The explicit mention of a day of the week will forward the date (only
if necessary) to reach that day of the week in the future.



Days of the week may be spelled out in full: `Sunday\', `Monday\',
`Tuesday\', `Wednesday\', `Thursday\', `Friday\' or `Saturday\'. Days
may be abbreviated to their first three letters, optionally followed by
a period. The special abbreviations `Tues\' for `Tuesday\', `Wednes\'
for `Wednesday\' and `Thur\' or `Thurs\' for `Thursday\' are also
allowed.



A number may precede a day of the week item to move forward
supplementary weeks. It is best used in expression like `third
monday\'. In this context, `last day\' or `next day\' is also
acceptable; they move one week before or after the day that day by
itself would represent. 





This means that the current behavoir is correct.

Description:
------------
The clients server is hosted by a third party running debian SMP Apache
and PHP 4.3.4.  The use of strtotime("next monday") skips monday the
1st and returns monday the 8th when run on Feb. 28th (tomorrow is a
leap day.)



The servers particulars:

[dali]$ uname -a

Linux dali 2.4.24-grsec+w+fhs5+gr1913+nfs+++p3+c3+bu+gr0b-v6.182 #1 SMP
Mon Jan 5 12:43:44 PST 2004 i686 unknown

[dali]$ date

Sat Feb 28 14:33:39 PST 2004

Reproduce code:
---------------
[dali]$ cat t1.php

<?

$start = strtotime('next monday');

echo ('Start timestamp: '.$start.'<br>'."\n");

$first = strtotime('first Monday',$start);

echo ('"First" Monday: '.date('l, M d Y',$first).'<br>'."\n");

$oneth = strtotime('1 Monday',$start);

echo ('"1" Monday: '.date('l, M d Y',$oneth).'<br>'."\n");

$next = strtotime('next Monday',$start);

echo ('"Next" Monday: '.date('l, M d Y',$next).'<br>'."\n");

$twoth = strtotime('2 Monday',$start);

echo ('"2" Monday: '.date('l, M d Y',$twoth).'<br>'."\n");

$third = strtotime('third Monday',$start);

echo ('"Third" Monday: '.date('l, M d Y',$third).'<br>'."\n");

$threeth = strtotime('3 Monday',$start);

echo ('"3" Monday: '.date('l, M d Y',$threeth).'<br>'."\n");

?>

Expected result:
----------------
[dali]$ php t1.php

Content-type: text/html

X-Powered-By: PHP/4.3.4



Start timestamp: 1078732800<br>

"Next" Monday: Monday, Mar 01 2004<br>

"First" Monday: Monday, Mar 01 2004<br>

"1" Monday: Monday, Mar 01 2004<br>

"Next" Monday: Monday, Mar 08 2004<br>

"2" Monday: Monday, Mar 08 2004<br>

"Third" Monday: Monday, Mar 15 2004<br>

"3" Monday: Monday, Mar 15 2004<br>

[dali]$ 





Actual result:
--------------
[dali]$ php t1.php

Content-type: text/html

X-Powered-By: PHP/4.3.4



Start timestamp: 1078732800<br>

"Next" Monday: Monday, Mar 08 2004<br>

"First" Monday: Monday, Mar 08 2004<br>

"1" Monday: Monday, Mar 08 2004<br>

"Next" Monday: Monday, Mar 15 2004<br>

"2" Monday: Monday, Mar 15 2004<br>

"Third" Monday: Monday, Mar 22 2004<br>

"3" Monday: Monday, Mar 22 2004<br>

[dali]$
