本文实例讲述了php实现的日历程序。分享给大家供大家参考。具体如下:

<?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']) ? date("Y"): $_GET["Year"];
$Month = empty($_GET['Month']) ? 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("Sun","Mon","Tue","Wed","Thu","Fri","Sat");
$Weekday_count = count($Weekday);
$daynum = 0;
$space = " ";
$col = 0;
////打印表格头部////
?>
<?php ////打印星期列表//// while(list(,$Weekvalue) = each($Weekday)) echo ""; echo ""; ////打印日期列表//// //当月份为4,6,9,11的时候,从数组末尾删除一个值,也就是删除31这个值. if($Month == 4 or $Month == 6 or $Month == 9 or $Month == 11) { array_pop($Maxday); $Maxday_count--; } //先判断月份是否为2月,如果是的话再判断年份是否为闰年,如果是的话就从数组尾部移除2个值,否则就移除3个值. if($Month == 2) { if($Year % 4 == 0) { array_pop($Maxday); array_pop($Maxday); $Maxday_count-=2; } else { array_pop($Maxday); array_pop($Maxday); array_pop($Maxday); $Maxday_count-=3; } } ////打印日期//// while($daynum < $Maxday_count) { echo ""; while(list($colnum,$Dayvalue) = each($Maxday)) { //判断当前日期为一星期中的哪一天 $DayWeek = date("w",strtotime($Year."-".$Month."-".$Dayvalue)); //当当前日期处于第1个,也就是每个月的第1天的时候,在它前面补上相应的空格子 if($Dayvalue == 1) for($i=0;$i<$DayWeek;$i++) echo $space;//打印每个月空出的几个格子 $daynum++; //当打印日期的时候与当前日期字符串进行比较,如果相等就将字体标为红色. if($Year.$Month.$Dayvalue == $Today) { $u1 = ""; $u2 = ""; } else { $u1 = ""; $u2 = ""; } if($DayWeek == 0 or $DayWeek == 6) $color = "red"; else $color = "black"; echo ""; //用本周第几天这个值加1,如果是7的倍数就换行退出此轮循环(换行打印) if(($DayWeek+1) % 7 == 0) { $col++; break; } } echo ""; } ?>

运行效果如下:

希望本文所述对大家的php程序设计有所帮助。
