PHP设计日历类一 （38），日历38

PHP设计日历类一 （38），日历38由两个文件组成：第一个test.php"calendar.class.php"; $calendar=new Calendar; $calendar->out();登录后复制第二个日历类：calendar.class.phpclass Calendar { private $year; //当前的年 private $month; //当前的月 private $start_weekday; //当月的第一天对应的是周几 private $days; //当前月一共多少天 function __construct(){ $this->year=isset($_GET["year"]) ? $_GET["year"] : date("Y"); $this->month=isset($_GET["month"]) ? $_GET["month"] : date("m"); $this->start_weekday=date("w", mktime(0, 0, 0, $this->month, 1, $this->year)); $this->days=date("t", mktime(0, 0, 0, $this->month, 1, $this->year)); } function out(){ echo ''; $this->chageDate("test.php"); $this->weeksList(); $this->daysList(); echo ''; } private function weeksList(){ $week=array('日','一','二','三','四','五','六'); echo ''; for($i=0; $i''.$week[$i].''; echo ''; } private function daysList(){ echo ''; //输出空格(当前一月第一天前面要空出来) for($j=0; $j->start_weekday; $j++) echo ' '; for($k=1; $k->days; $k++){ $j++; if($k==date('d')) echo ''.$k.''; else echo ''.$k.''; if($j%7==0) echo ''; } //后面几个空格 while($j%7!==0){ echo ' '; $j++; } echo ''; } private function prevYear($year, $month){ $year=$year-1; if($year ) $year = 1970; return "year={$year}&month={$month}"; } private function prevMonth($year, $month){ if($month == 1) { $year = $year -1; if($year ) $year = 1970; $month=12; }else{ $month--; } return "year={$year}&month={$month}"; } private function nextYear($year, $month){ $year = $year + 1; if($year > 2038) $year = 2038; return "year={$year}&month={$month}"; } private function nextMonth($year, $month){ if($month==12){ $year++; if($year > 2038) $year=2038; $month=1; }else{ $month++; } return "year={$year}&month={$month}"; } private function chageDate($url=""){ echo ''; echo ''.$this->prevYear($this->year, $this->month).'">'.''.''; echo ''.$this->prevMonth($this->year, $this->month).'">'.''.''; echo ''; echo ''; echo ''.$url.'?year=\'+this.options[selectedIndex].value+\'&month='.$this->month.'\'">'; for($sy=1970; $sy ; $sy++){ $selected = ($sy==$this->year) ?
