Calendar program implemented by php

This article mainly introduces the calendar program implemented by php, which can implement basic calendar display and real-time query functions, which is of great practical value, for more information about calendar programs implemented by php, see the example in this article. Share it with you for your reference. The details are as follows:

<? Php /// determine whether $ Year and $ Month are empty. if they are empty, the current date of the system is obtained, otherwise, use $ _ GET to GET $ Year = empty ($ _ GET ['Year'])? Date ("Y"): $ _ GET ["Year"]; $ Month = empty ($ _ GET ['month'])? Date ("m"): $ _ GET ["Month"]; // GET the current date /// $ Today = date ("Ymj "); //// initialization date array //// $ Maxday = array ("1", "2", "3", "4", "5", "6 ", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16 ", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26 ", "27", "28", "29", "30", "31"); $ Maxday_count = count ($ Maxday ); //// initialize the array of weeks //// $ Weekday = array ("Sun", "Mon", "Tue", "Wed", "Thu", "Fri ", "Sat"); $ Weekday_count = count ($ Weekday); $ daynum = 0; $ space =" "; $ Col = 0; // Print the table header ///?>
 
  "; $ U2 ="
  

  
The running effect is as follows:
