example:
include_once '/class/calendar.class.php';
$simple_example = new calendar();
print($simple_example->output_calendar());

代码如下

复制代码

class calendar{
var $date;
var $year;
var $month;
var $day;

var $week_start_on = false;
var $week_start = 7;// sunday

var $link_days = true;
var $link_to;
var $formatted_link_to;

var $mark_today = true;
var $today_date_class = 'today';

var $mark_selected = true;
var $selected_date_class = 'selected';

var $mark_passed = true;
var $passed_date_class = 'passed';

var $highlighted_dates;
var $default_highlighted_class = 'highlighted';

/* constructor */
function calendar($date = null, $year = null, $month = null){
  $self = htmlspecialchars($_server['php_self']);
  $this->link_to = $self;

  if( is_null($year) || is_null($month) ){
   if( !is_null($date) ){
    //-------- strtotime the submitted date to ensure correct format
    $this->date = date("y-m-d", strtotime($date));
   } else {
    //-------------------------- no date submitted, use today's date
    $this->date = date("y-m-d");
   }
   $this->set_date_parts_from_date($this->date);
  } else {
   $this->year  = $year;
   $this->month = str_pad($month, 2, '0', str_pad_left);
  }
}

function set_date_parts_from_date($date){
  $this->year  = date("y", strtotime($date));
  $this->month = date("m", strtotime($date));
  $this->day  = date("d", strtotime($date));
}

代码如下

复制代码

//------------------------------------------------- start table, caption
$output = "

";
  $output .= " ";

  $col = '';
  $th = '';
  for( $i=1,$j=$this->week_start,$t=(3+$this->week_start)*86400; $i<=7; $i++,$j++,$t+=86400 ){
   $localized_day_name = gmstrftime('%a',$t);
   $col .= "";
   $th .= " ";
   $j = ( $j == 7 )? 0 : $j;
  }

  //------------------------------------------------------- markup columns
  $output .= $col;

  //----------------------------------------------------------- table head
  $output .= " ";
  $output .= " ";

  $output .= $th;

  $output .= " ";
  $output .= " ";

  //---------------------------------------------------------- start tbody
  $output .= " ";
  $output .= " ";

" . ucfirst(strftime("%b %y", $month_start_date)) . "
" . strtoupper($localized_day_name{0}) ."

";
  }

  //--------------------------------------------------- loop days of month
  for($day=1,$cell=$prepend+1; $day<=$days_in_month; $day++,$cell++){

   /*
   if this is first cell and not also the first day, end previous row
   */
   if( $cell == 1 && $day != 1 ){
    $output .= " ";
   }

   //-------------- zero pad day and create date string for comparisons
   $day = str_pad($day, 2, '0', str_pad_left);
   $day_date = $year . "-" . $month . "-" . $day;

   //-------------------------- compare day and add classes for matches
   if( $this->mark_today == true && $day_date == date("y-m-d") ){
    $classes[] = $this->today_date_class;
   }

   if( $this->mark_selected == true && $day_date == $this->date ){
    $classes[] = $this->selected_date_class;
   }

   if( $this->mark_passed == true && $day_date < date("y-m-d") ){
    $classes[] = $this->passed_date_class;
   }

   if( is_array($this->highlighted_dates) ){
    if( in_array($day_date, $this->highlighted_dates) ){
     $classes[] = $this->default_highlighted_class;
    }
   }

   //----------------- loop matching class conditions, format as string
   if( isset($classes) ){
    $day_class = ' class="';
    foreach( $classes as $value ){
     $day_class .= $value . " ";
    }
    $day_class = substr($day_class, 0, -1) . '"';
   } else {
    $day_class = '';
   }

   //---------------------------------- start table cell, apply classes
   $output .= " ";

   //----------------------------------------- unset to keep loop clean
   unset($day_class, $classes);

   //-------------------------------------- conditional, start link tag
   switch( $this->link_days ){
    case 0 :
     $output .= $day;
    break;

    case 1 :
     if( empty($this->formatted_link_to) ){
      $output .= "link_to . "?date=" . $day_date . "">" . $day . "";
     } else {
      $output .= "formatted_link_to, strtotime($day_date)) . "">" . $day . "";
     }
    break;

代码如下	复制代码
//---------------------------------------------- initialize week counter $weeks = 1; //--------------------------------------------------- pad start of month //------------------------------------ adjust for week start on saturday for($i=1;$i<=$prepend;$i++){ $output .= "

";

   //------- if this is the last cell, end the row and reset cell count
   if( $cell == 7 ){
    $output .= " ";
    $cell = 0;
   }

  }

  //----------------------------------------------------- pad end of month
  if( $cell > 1 ){
   for($i=$cell;$i<=7;$i++){
    $output .= " ";
   }
   $output .= " ";
  }

  //--------------------------------------------- close last row and table
  $output .= " ";
  $output .= "

代码如下	复制代码
case 2 : if( is_array($this->highlighted_dates) ){ if( in_array($day_date, $this->highlighted_dates) ){ if( empty($this->formatted_link_to) ){ $output .= "link_to . "?date=" . $day_date . "">"; } else { $output .= "formatted_link_to, strtotime($day_date)) . "">"; } } } $output .= $day; if( is_array($this->highlighted_dates) ){ if( in_array($day_date, $this->highlighted_dates) ){ if( empty($this->formatted_link_to) ){ $output .= ""; } else { $output .= ""; } } } break; } //------------------------------------------------- close table cell $output .= "

";

  //--------------------------------------------------------------- return
  return $output;

}

}

//调用日期生成类的方法

代码如下	复制代码
include_once '/class/calendar.class.php'; $simple_example = new calendar(); print($simple_example->output_calendar());
