PHP设计日历类一 （38），日历38
由两个文件组成：
第一个test.php
php
include "calendar.class.php";
$calendar=new Calendar;
$calendar->out();
第二个日历类：calendar.class.php
php
class 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; $i)
echo '| '.$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; $j<$this->start_weekday; $j++)
echo '| | ';
for($k=1; $k<=$this->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 < 1970)
$year = 1970;
return "year={$year}&month={$month}";
}
private function prevMonth($year, $month){
if($month == 1) {
$year = $year -1;
if($year < 1970)
$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, $this->month).'">'.'<'.' | ';
echo '';
echo '';
echo ' | ';
echo ''.$this->nextYear($this->year, $this->month).'">'.'>>'.' | ';
echo ''.$this->nextMonth($this->year, $this->month).'">'.'>'.' | ';
echo '
';
}
}
