Two php date control classes_PHP tutorial

由于工作需要我找了二个时间日期控制，这个不用js只要php实现的，因为要带参考查询所以操作了操作，有需要的朋友可以参考一下哦，我自己用的是第二个，所以第二个己作了修改。

class Calendar
{
var $month;
var $year;

function __construct($year,$month)
{
$this->year=$year;
  $this->month=$month;
 }

 function endday()
 {
  $daydate=date("d",mktime(0,0,0,$this->month,35,$this->year));
  $endday=35-$daydate;
  return $endday;
 }
 
 function oneday_week()
 {
  $oneday_week=date("w",mktime(0,0,0,$this->month,1,$this->year));
  return $oneday_week;
 }
 
 function title_link()
 {
  if(!isset($this->month) && !isset($this->year))
  {
   $this->year  = date("Y");
   $this->month = date("m");
        }
       
 
  $lastmonth=$this->month-1;
  $nextmonth=$this->month+1;
  $lastyear=$this->year;
  $nextyear=$this->year;

        if($this->month <= 1)
{
$lastmonth=12;
$nextmonth=$this->month+1;
   $lastyear=$this->year-1;
   $nextyear=$this->year;
  }
        elseif ($this->month >= 12)
        {
         $lastmonth=$this->month-1;
         $nextmonth=1;
   $lastyear=$this->year;
   $nextyear=$this->year+1;
        }

        $str ="
