我如何在页面上显示该月的日历？谢谢！

Question

一个最简单的日历程序（php4.3.3，自己修改）：
<?php
function build_calender_table($year=0,$month=0,$day=0)
{
global $PHP_SELF;
$cal="";

$year=$_GET['year'];
$month=$_GET['month']; if($year==0) $year=date('Y')+0;
if($month==0) $month=date('m')+0;
if($day==0) $day=date('d'+0);

$pyear=($month==1?$year-1:$year);
$pmonth=($month==1?12:$month-1);

$nyear=($month==12?$year+1:$year);
$nmonth=($month==12?1:$month+1);

$firstday=mktime(0,0,0,$month,1,$year);
$skip=date('w',$firstday);
$dim=date('t',$firstday);
$rows=ceil(($skip+$dim)/7);

$cal.="\n<table width=160 border=0 cellpadding=1 cellspacing=1 align=center>";
$cal.="\n<tr><td colspan=7 align=center>";
$cal.="<a href='"."$PHP_SELF?year=$pyear&month=$pmonth"."' onclick='javascript:documnet.form1.mon.value=1'>上月</a>&nbsp;";
$cal.=$year.'/'.$month;
$cal.="&nbsp;<a href='"."$PHP_SELF?year=$nyear&month=$nmonth"."'>下月</a>";
$cal.="\n</td></tr>";
$cal.="\n<tr align=center>";
$cal.="\n<td>日</td><td>一</td><td>二</td><td>三</td><td>四</td><td>五</td><td>六</td>";
$cal.="\n</tr>";

for($row=0;$row<$rows;$row++)
{
$cal.="\n<tr align=center>";
for($col=0;$col<7;$col++)
{
$cur=$row*7+$col-$skip+1;
$cal.="\n<td";
if($year=(int)date('Y')&&$month==(int)date('m')&&$cur==(int)date('d')) $cal.=" bgcolor=#d0d0d0";
$cal.=">";
if($row*7+$col<$skip) $cal.="$nbsp;";
else
{
if($cur>$dim) $cal.="&nbsp;";
else
{
if($year=(int)date('Y')&&$month==(int)date('m')&&$cur==$day) $cal.="</b>";
$cal.="<a href='"."$PHP_SELF?year=$year&month=$month&day=$cur"."'>".$cur."</a>";
if($year=(int)date('Y')&&$month==(int)date('m')&&$cur==$day) $cal.="</b>";
}
}
$cal.="</td>";
}
$cal.="\n</tr>";
}
$cal.="\n</table>";
echo $cal;
}
build_calender_table();
?>

这是一个使用phplib模板类的例子
<?php
include "template.inc";
$str = "<table border>
<colgroup span=5 align=right></colgroup>
<colgroup span=2 align=right style='color:red'></colgroup>
<tr><th>一</th><th>二</th><th>三</th><th>四</th><th>五</th><th>六</th><th>日</th></tr>
<!-- BEGIN Month -->
<tr>
<!-- BEGIN Date -->
<td bgcolor='{color}'>{data}</td>
<!-- END Date -->
</tr>
<!-- END Month -->
</table>
";
$mode = 7;
$n = date("t");
$w = date("w",mktime(0,0,0,date("m"),1,date("Y")));
$w = $w==0?7:$w;
$j = date("j");
$tpl = new template;
$tpl->halt_on_error = "report";
$tpl->set_var("hand",$str);
$tpl->set_block("hand","Month","row");
$tpl->set_block("Month","Date","col");
$d = $i = 1;
while($i <= $n) {
  if($d < $w)
    $tpl->set_var("data","&#160");
  else {
    $tpl->set_var("color",($i==$j?"#0000FF":""));
    $tpl->set_var("data",$i++);
  }
  $tpl->parse("col","Date",true);
  if($d++ % $mode == 0) {
    $tpl->parse("row","Month",true);
    $tpl->set_var("col");
  }
}
if(--$d % $mode > 0) {
  while($d++ % $mode) {
    $tpl->set_var("data","&#160");
    $tpl->parse("col","Date",true);
  }
  $tpl->parse("row","Month",true);
}
$tpl->parse("out","hand",true);
$tpl->p(out);
?>
