PHP production perpetual calendar, php perpetual calendar

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
The role of $days: knowing how many days there are in the month to be processed, you can output the number of days through a loop

The role of $dayofweek: Only by knowing the day of the week on the 1st of each month can we know how many spaces (blanks) need to be output before outputting the number of days

The final rendering is as follows:

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

Copy code The code is as follows:

/**

class Calendar{
Protected $_table;//table
Protected $_currentDate;//Current date
Protected $_year; //Year
Protected $_month; //Month
Protected $_days; //Number of days in a given month
protected $_dayofweek;//What day of the week is the 1st of a given month
/**

           $this->_table="";
          $this->_year = isset($_GET["y"])?$_GET["y"]:date("Y");

                 $this->_month=1;
