[PHP] Bug with mktime??
Hi
I have been using mktime() to determine the next 12 months for a
program, and i have discovered what seems a bug in the function.
The following code...
?php
for($i=0;$i 12;$i++){
$currentDate = date(d m Y,mktime(0, 0, 0,date(m)+$i , date(d),
date(Y)));
$currentDateArray = explode( ,$currentDate);
$currentMonth = $currentDateArray[1];
$currentYear = $currentDateArray[2];
echo $i : $currentMonth : $currentYear br;
}
gives the following output:
$i : Month: Year
0 : 08 : 2004
1 : 10 : 2004
2 : 10 : 2004
3 : 12 : 2004
4 : 12 : 2004
5 : 01 : 2005
6 : 03 : 2005
7 : 03 : 2005
8 : 05 : 2005
9 : 05 : 2005
10 : 07 : 2005
11 : 07 : 2005
This output has a problem.
Does anyone have any suggestions on what other functions I could use
other than mktime to build dates ???
Cheers
John Clegg

Try using date('n'). Leading zeros are interpreted in octal.

Your bug is being caused by short months. If you ask mktime() to give
you the 31st day of november, it will assume you mean the 1st of
december. You can see more clearly what's going on if you shorten your
code, like so:
for($i=0;$i 12;$i++) {
echo {$i}: ;
echo date(d m Y,mktime(0, 0, 0,date(m)+$i , date(d), date(Y)));
echo 'br';
}
It's a good thing you're trying this today; if you had tried it a few
days ago, you wouldn't have had any idea that your method wasn't
working.
