Two php date control class instances, php date class instances

The examples in this article describe two PHP date control classes. Share it with everyone for your reference. The specific analysis is as follows:

Due to work needs, I found two time and date controls. This does not require JS and only needs to be implemented in PHP. Because it requires a reference query operation, interested friends can refer to it. I use the second one myself, so the second one is used. I have made modifications myself.

Example 1, the code is as follows:

Copy code The code is as follows:

<?php
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 ="

<<<

";
  $str.="

".$this->year."--".$this->month."

";
  $str.="

>>>

";
  return $str;
 }
 
 function Show_Calendar()
 {
        echo "".$this->title_link()."";
        $weekarray=array("日","一","二","三","四","五","六");
        
        for($k=0;$k<=6;$k++)
{
echo "";
        }
        echo "";
        
        for($i=0;$i<=5;$i++)
        {
         echo "";
         for($j=1;$j<=7;$j++)
{
$math=( $j - $this->oneday_week() ) + 7 * $i;
    
          echo "";
                                                                    echo "";
          }
echo "

".$weekarray[$k]."

";
    
          if($math <= $this->endday() and $math>=1)
     {
   echo $math;
     }
    
         echo "

";
}
}
$calendar=new Calendar($_GET['year'],$_GET['month']);
$calendar->month=$_GET['month'];
$calendar->year=$_GET['year'];
$calendar->Show_Calendar();
?>

Example 2, the code is as follows:

Copy code The code is as follows:

header("content-type:text/html;charset=utf-8");
?>

 

if(!emptyempty($_GET)){
    $year = isset($_GET['year'])?$_GET['year']:date('y');
    $month = isset($_GET['month'])?$_GET['month']:date('m');
 $day = isset($_GET['day'])?$_GET['day']:date('d');
}
if(emptyempty($year)){
    $year = date('Y');
}
if(emptyempty($month)){
    $month = date('m');
}
 
if(emptyempty($month)){
    $days = date('d');
}
 
$start_weekday = date('w',mktime(0,0,0,$month,1,$year));
//echo $start_weekday;
$days = date('t',mktime(0,0,0,$month,1,$year));
//echo $days;
$week = array('日','一','二','三','四','五','六');
$i = 0;
$k = 1;
$j = 0;
echo '';
echo '';
echo '';
for($i = 0;$i < 7;$i++){
    echo '';
}
echo '';
echo '';
for($j = 0;$j < $start_weekday;$j++){
    echo '';
}
while($k <= $days){
    if($k == $day){
        echo '';
    }else{
        echo '';
    }
    if(($j+1) % 7 == 0){
        echo '';
    }
    $j++;
    $k++;
}
while($j % 7 != 0){
    echo '';
    $j++;
}
echo '';
 
echo '';
echo "';

echo '';

echo '';
echo '

'; echo ' '; echo ''; for($start_year = 1970;$start_year<2039;$start_year++){  $selected='';  if( $year== $start_year ) { $selected='selected'; }  echo ''.$start_year.''." nt"; } echo ''; echo ''; for($start_month = 1;$start_month<=12;$start_month++){  $selected='';  if( $month== $start_month ) { $selected='selected';}  echo ''.$start_month.''." nt"; } echo ''; /*echo '月';*/ /*echo '';*/ echo ' '; echo '			".'>>'.'

';
 
function lastYear($year,$month){
 $year = $year-1;
 return "year=$year&month=$month";
}
function lastMonth($year,$month){
 if($month == 1){
$year = $year -1;
$month = 12;
}else{
$month--;
}
return "year=$year&month=$month";
}
function nextYear($year,$month){
$year = $year+1;
return "year=$year&month=$month";
}
function nextMonth($year,$month){
if($month == 12){
$year = $year +1;
$month = 1;
}else {
$month++;
}
return "year=$year&month=$month";
}

?>

I hope this article will be helpful to everyone’s PHP programming design.
