To get the number of days for a specific month, I use:
// $current_month is the month under question
$next_month = $current_month + 1;
I use this
$next_month = $current_month + 1;
$next_month_1= mktime(0, 0, 0, $next_month, 1, date(Y) );
$current_month_1= mktime(0, 0, 0, $current_month, 1, date(Y) );
$mdays = ($current_month_1 - $next_month_1)/(3600*24);
It's much more easier if you use DateTime and DateInterval class

Hi, All
To bring a work-around into this discussion I myself would not see it
as a good way to do it like that - even if the documentation provides
some information around that.
Here's what I have done in all new projects I worked with time-calculation:
@Tedd: Lets pick up your first example and work with the
DateTime-Object instead:
$date = new DateTime($year . '-' . $current_month . '-1');
$date-add( new DateInterval( 'P1M' ) ); // Add a period of 1 month to
the date-instance (haven't tried that with the 30th of Jan ... would
be kind-of interesting)
$days_in_current_month = $date-format('j'); // Get the date of the month
As this does not solve the problem (as we still should update the
documentation or the code if it does not match) it's not a solution,
but a suggestion to coding-style at all.
It seems a bit cleaner to me as you don't have to worry about the 13th
month, time-zones or other things that can be difficult to calculate
yourself.
Bye

I think you'd need to subtract it with 1 day
date_create(date('Y-m'))-add(new DateInterval('P1M'))-sub(new
DateInterval('P1D'))-format('d');

Anybody got eaccelerator and/or magickwand compiling for PHP5.4?
I've got a nice new machine all set up, and would like to take it straight to
Apache 2.4.1 and PHP5.4, but I'd also like to keep the same library setup as the
5.3 setup.

Oh, I see what you're saying now. Well, using getdate(), how else would
you think to pass the parameter to get the last day other than using the
current month and the last day (which would then obviously be overkill, of
course).
All of this aside, though, you may instead want to use something along the
lines of date('d',strtotime('last day of this month')); in tandem with your
date formatting.

Mike: Very well put. You say: Huh? The 0th day of next month *is* the last day of the current month, which gives you the number of days in the current month. That IS exactly what I am saying. But why does anyone have to use the next month to figure out how many days there are are in this month? Do you see my point? It would have been better if one could use: $what_date = getdate(mktime(0, 0, 0, $this_month, 0, $year)); $days_in_this_month = $what_date['nday']; // note an additional key for getdate() But instead, we have to use: $next_month = $this_month +1; $what_date = getdate(mktime(0, 0, 0, $next_month, 0, $year)); $days_in_this_month = $what_date['mday']; Additionally, there's a perception problem. You say that 0 of the next month *is* the last day of the current month -- as such, apparently months overlap in your (and Dan's) explanation. Well... I agree with both of you, but my objection is having to increase the month value by one to get the number of days in the current month. That's all I was saying. Side-point: I find it interesting that getdate() has all sorts of neat descriptions for the current month (such as, what weekday a numbered day is), but lacks how many days are in the month. Doesn't that seem odd? Cheers, tedd _ tedd.sperl...@gmail.com http://sperling.com I am surprised that nobody has come up with this one yet. $what_date = getdate(mktime(0, 0, 0, $this_month, 35, $year)); $days_in_this_month = 35 - $what_date['mday']; Even a one liner... $what_date = getdate(mktime(0,0,0,$this_month,35,$year)-(35 * 86400)); Sorry, had my math backwards... $what_date = getdate((35 * 86400)-mktime(0,0,0,$this_month,35,$year)); Spoke too soon. Since you have to know the output of getdate() to calculate the minus figure... I guess that won't work. Use the first one that I suggested. -- Jim Lucas http://www.cmsws.com/ http://www.cmsws.com/examples/ http://www.bendsource.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Oh, I see what you're saying now. Well, using getdate(), how else would you
think to pass the parameter to get the last day other than using the current
month and the last day (which would then obviously be overkill, of course).
Well.. you could use any number that exceeds 31 -- or -- as I would have
suggested if it had been up to me, zero day would provide the number of days in
*that* month rather than the number of days in the previous month, which was
the point of my post.
All of this aside, though, you may instead want to use something along the
lines of date('d',strtotime('last day of this month')); in tandem with your
date formatting.
That's a good idea, but
date('d',strtotime('last day of this month'));
gives me the number of days in *this* month, but not the next, or previous,
month.
I need the result to be whatever date was selected -- something like:
$number_days = date('d',strtotime('last day of April, 2014'));
But that doesn't work.
You see, I need something that makes sense to students. The idea that you have
to use the zero day (whatever that is) of the next month to see how many days
there are in this month is strange and confusing -- again my point.
Thus far, the following looks better than what I came up with::
$what_date = getdate(mktime(0, 0, 0, $mon, 32, $year));
$days_in_month = 32 - $what_date['mday'];
But it's still strange.
I was using:
// get the last day of the month
$cont = true;
$tday = 27;
while (($tday = 32) ($cont))
{
$tdate = getdate(mktime(0,0,0,$mon,$tday,$year));
if ($tdate[mon] != $mon)
{
$lastday = $tday - 1;
$cont = false;
}
$tday++;
}
It made sense, but was too long. I figured there should be something better and
easier to explain -- but I'm still looking.
Cheers
