Re: [PHP] DateTime wierdness
echo date(m-d-y,mktime(0, 0, 0, 14, 14, 2012));
this outputs 02-14-13 also so my guess is that it is being interpreted
the same as 12/14/2012 +2 months
echo date(m-d-y,mktime(0, 0, 0, 1, 45, 2012)); outputs
02-14-12
which is 1/1/12 +45 days

Can someone explain to me this weierdness I see when using the
DateTime module of PHP.
Here I send 14/14/2012 which is not a valid date, and I would expect
to recieve false, but instead, it looks like it wrapping to the next
year, as if 14 monthas are 1 year and 2 months. That isn't what's
supposed to happen, or is it?
$ echo ?php var_dump(DateTime::createFromFormat('j/n/Y',
'14/14/2012')); ? |php
object(DateTime)#1 (3) {
[date]=
string(19) 2013-02-14 13:20:22
[timezone_type]=
int(3)
[timezone]=
string(20) America/Buenos_Aires
}

Re: [PHP] DateTime wierdness
OK. So what would be a good way to validate a date?

Re: [PHP] DateTime wierdness
actually this would work well ... compare what they send with the output of
the formatdate
function checkDateTime($data) {
if (date('Y-m-d H:i:s', strtotime($data)) == $data) {
return true;
} else {
return false;
}
}

Well, I did somethin similar...
$arDate = explode(/, $nacimiento);
if(!checkdate($arDate[1], $arDate[0], $arDate[2]))
$nacimiento = '';
Just need to set the variable $nacimiento to the empty string if it's
not a valid date.
Thanks anyway,

I don't know how it came to be, but a lot of people rely on this
behaviour. It does make sense if you squint at it a bit -- trust that
the programmer meant what they said and deliver something useful,
leave error checking up to the programmer. I'm a bit ambivalent about
it, personally, but the way it's implemented does seem more flexible.
