I do this:
if (!extension_loaded('calendar'))
{
/*
* cal_days_in_month($month, $year)
* Returns the number of days in a given month and year,
* taking into account leap years.
*
* $month: numeric month (integers 1-12)
* $year: numeric year (any integer)
*
* Prec: $month is an integer between 1 and 12, inclusive
* $year is an integer.
* Post: none
*/
function cal_days_in_month($month, $year)
{
return $month == 2 ? $year % 4 ? 28 : 29 : ($month % 7 % 2 ? 31 : 30);
}
}
