PHP perpetual calendar implementation code_PHP tutorial

Key points of using PHP to implement the perpetual calendar function:

•Get the total number of days in the current month to be processed $days
•Get the day of the week that the first day of the month to be processed is $dayofweek
$days Function: If you know how many days there are in the month to be processed, you can output the number of days through a loop

Function of $dayofweek: Only if you know the day of the week on the 1st of each month, can you know that you need to output the number of days before outputting it. How many spaces (blank)

The final rendering is as follows:



The code of "perpetual calendar class" is as follows:

Copy code The code is as follows:
