一直喜欢php下的日历实现代码，测试效果不错
复制代码 代码如下:
<?php
function calendar()
{
if($_GET['ym'])
{
$year = substr($_GET['ym'],0,4);
$month = substr($_GET['ym'],4,(strlen($_GET['ym'])-4));
if($month>12)
{
$year += floor($month/12);
$month = $month % 12;
}
if($year > 2030) $year = 2030;
if($year < 1980) $year = 1980;
}
$year = isset($year) ? $year : date('Y');
$month = isset($month) ? $month : date('n');
if($year==date('Y') && $month==date('n')) $today = date('j');
if($month-1 == 0)
$prevmonth = ($year - 1)."12";
else $prevmonth = $year.($month - 1);
if($month+1 == 13)
$nextmonth = ($year+1)."1";
else $nextmonth = $year.($month+1);
$prevyear = ($year - 1).$month;
$nextyear = ($year + 1).$month;
echo <<<VKN
<table width="200" border="0" cellpadding="2" cellspacing="2">
<tr>
<td class="weekday"><a href="?ym=$prevyear"><<</a></td>
<td class="normalday"><a href="?ym=$prevmonth"><</a></td>
<td colspan="3" class="normalday">$year - $month</td>
<td class="normalday"><a href="?ym=$nextmonth">></a></td>
<td class="weekday"><a href="?ym=$nextyear">>></a></td>
</tr>
<tr>
<td width="27" class="weekday">日</td>
<td width="27" class="normalday">一</td>
<td width="27" class="normalday">二</td>
<td width="27" class="normalday">三</td>
<td width="27" class="normalday">四</td>
<td width="27" class="normalday">五</td>
<td width="27" class="weekday">六</td>
</tr>
VKN;
$nowtime = mktime(0,0,0,$month,1,$year);//当月１号转为秒
$daysofmonth = date(t,$nowtime);//当月天数
$weekofbeginday = date(w,$nowtime);//当月第一天是星期几
$weekofendday = date(w,mktime(0,0,0,$month+1,0,$year));//当月最后一天是星期几
$daysofprevmonth = date(t,mktime(0,0,0,$month,0,$year));//上个月天数
$count = 1;//计数
//列出上月后几天
for($i = 1 ; $i <= $weekofbeginday ; $i++)
{
echo "<td class='othermonth'>".($daysofprevmonth-$weekofbeginday+$i)."</td>";
$count++;
}
//当月全部
for($i = 1 ; $i <= $daysofmonth ; $i++)
{
$css = ($count%7==0 || $count%7==1)?"weekday":"normalday";
if($i == $today) $css .= "today";
echo "<td class='".$css."'>".$i."</td>";
if($count%7==0) echo "</tr><tr>";
$count++;
}
//下月前几天
for ($i = 1;$i <= 6-$weekofendday;$i++)
{
echo "<td class='othermonth'>".$i."</td>";
}
echo <<<VKN
<tr>
<td colspan="7"></td>
</tr>
</table>
VKN;
}
?>
