The essentials of using PHP to realize the calendar function:
• Get the total number of days of the month currently to be processed $days
• Get the number of the month that is currently being processed is the week $dayofweek
$days role: Know how many days to process the month, you can output the number of days by cycle
$dayofweek role: Only know the number of days per month is the day of the week, to know how many spaces to output before the number (blank)
