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：
复制代码 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();
希望本文所述对大家的php程序设计有所帮助。
