This article describes the calendar program implemented in php. Share it with everyone for your reference. The details are as follows:

<&#63;php
////判断$Year和$Month是否为空,如果为空就获取系统当前日期,否则用$_GET获取
$Year = empty($_GET['Year']) &#63; date("Y"): $_GET["Year"];
$Month = empty($_GET['Month']) &#63; date("m"): $_GET["Month"];
////获取当前日期////
$Today = date("Ymj");
////初始化日期数组////
$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);
////初始化星期数组////
$Weekday = array("<font color='red'>Sun</font>","Mon","Tue","Wed","Thu","Fri","<font color='red'>Sat</font>");
$Weekday_count = count($Weekday);
$daynum = 0;
$space = "<td> </td>";
$col = 0;

  if($Dayvalue == 1)

  //用本周第几天这个值加1,如果是7的倍数就换行退出此轮循环(换行打印)
