PHP实现的简单日历类

本文实例讲述了PHP实现的简单日历类。分享给大家供大家参考。

具体实现代码如下：

date_default_timezone_set("etc/gmt-8"); 

header("Content-type: text/html; charset=utf-8"); 

class calendar{ 

var $t = array(); 

var $datesofmonth = array('1'=>'31','2'=>'28','3'=>'31','4'=>'30','5'=>'31','6'=>'30','7'=>'31','8'=>'31','9'=>'30','10'=>'31','11'=>'30','12'=>'31'); 

var $y,$m,$d; 

function set($time){ 

$this->t = getdate($time); 

$this->y = $this->t['year']; 

$this->m = $this->t['mon']; 

$this->d = date('d',$time); 

} 

function isrun(){ 

return ($this->y%400==0 || ($this->y%4==0 && $this->y%100==0)) ? 1 : 0; 

} 

function first(){ 

$time = mktime(0,0,0,$this->m,1,$this->y); 

$time = getdate($time); 

return $time['wday']; 

} 

function html(){ 

$isrun = $this->isrun(); 

$this->datesofmonth[2] = $isrun==1 ? 29: 28; 

$html .= "<table style='border:solid 1px black;'>n"; 

$html .= "<tr><th><a href=''>上一月</a></th><th colspan='5'>{$this->y}年 {$this->m}月</th><th><a href=''>下一月</a></th><tr>n"; 

$html .= "<tr><td>星期天</td><td>星期一</td><td>星期二</td>jb51.net<td>星期三</td><td>星期四</td><td>星期五</td><td>星期六</td></tr>n"; 

$html .= "<tr>n"; 

$first = $this->first(); 

for($i=0; $i<$first; $i++){ 

$html .= "<td></td>"; 

} 

$count = $this->datesofmonth[$this->m]+$first; 

for ($i=1; $i<= $this->datesofmonth[$this->m]; $i++){ 

$style = $i==$this->d ? ' style="color:red;font-weight:bold;"' : '' ; 

$html .= "<td align='center'{$style}>$i</td>"; 

if (($i==7%$first || ($i+$first)%7==0) && $i<$count){ 

$html .= "</tr>n<tr>"; 

} 

} 

$count = 7-$count%7; 

if ($count<7){ 

for ($i=0; $i<$count; $i++){ 

$html .= "<td></td>"; 

} 

} 

$html .= "</tr>n"; 

$html .= "</table>n"; 

return $html; 

} 

} 

$calendar = new calendar(); 

$calendar->set(time()); 

echo $calendar->html();
