function.html_select_date.php bug?

Hi,

http://cvs.php.net/co.php/smarty/libs/plugins/function.html_select_date.php?r=1.29#201

I think there's a bug in this line. It now reads:
'selected'   => $a=$time[1] ? strftime($month_value_format, mktime(0,
0, 0, (int)$time[1], 1, 2000)) : '',

I think this would be better:

'selected'   => $time[1]>0 ? strftime($month_value_format, mktime(0,
0, 0, (int)$time[1], 1, 2000)) : '',

I don't understand why $a should be assigned as it is isn't used later
on in the code. And because $time[1] doesn't always have to be 0 (as
is the case when your date comes out of the database like 0000-00-00)
this results in december to be selected.
To explain this: The value of $time[1] is 00 then, which results in
true for the check $a=$time[1], which results in
strftime($month_value_format, mktime(0, 0, 0, (int)$time[1], 1, 2000))
being executed. And because mktime sees (int)$time[1] as 0, it thinks
it should selected the last month of the previous year resulting in
december to be selected.
You could also use (int) $time[1] instead of $time[1] > 0

Greetings,

Yuri
