公司由于某些原因,需要给一个客户小儿子做个主页,其中需要像册和日记本,而且日记本当得有个日历.. 所以我~~~~

网络日记再加些扩展就成了博客了!

这个只程序只是显示日历,按日期索引还没有做,需要进一步分析.. 这个日历有几个关键算法,几个关键算法掌握了其实这个程序就算是简单的了!

<?
$year = $_GET[y];
$month = $_GET[m];

if($month == null) $month = date("m");
if($day == null) $day = date("d");
if($year == null) $year = date("Y");

$weekOneDay = date("w",mktime(0,0,0,$month,1,$year)); //算出本月份第一天是周几??
$dayNum = date("t",mktime(0,0,0,$month,1,$year)); //取得本月的天数
$weekNum = ceil(($dayNum+$weekOneDay+1)/7); //算出本月份的周数!!

//echo $weekOneDay;
//echo $dayNum;
//echo $weekNum;
//echo $day;
