Assignment -- create this calendar.
The following are the functions you will need to complete this project.
// get current date
$current_date = getdate();
// get numeric month (i.e., 1-12)
$mon = $current_date["mon"];
// get alpha month (i.e., January)
$month = $current_date["month"];
// get four digit year (i.e., 2012)
$year = $current_date["year"];
// create a date by using the getdate() and mktime() functions
$what_date = getdate(mktime(0, 0, 0, $mon, 1, $year));
//get the month selected
$month = $what_date["month"];
// get the first weekday of that month
$first_week_day= $what_date["wday"];
// get the number of days in that month
// This is done by using the date('t') and mktime() functions and
// increasing the current month by +1
$days_in_month = date('t', mktime(0, 0, 0, $next_month, 0, $year))
