一个简单的php Calender(日历),解决了2038问题,这样在32位机和64位机上都可以用了,代码很简单,方便修改

php calender(日历)二个版本代码示例(解决2038问题)



注意32位机有2038问题,所以32位服务器的年限范围1970年~2038年

我们还可以使用DateTime来规避这个问题(这样与32位64位无关了)

复制代码 代码如下:


/**
 *
 * 我的日历
 * date_default_timezone_set date mktime
 * @param int $year
 * @param int $month
 * @param string $timezone
 * @author fc_lamp
 * @blog: fc-lamp.blog.163.com
 */
function myCalender($year = '', $month = '', $timezone = 'Asia/Shanghai')
{

 date_default_timezone_set ( $timezone );
 $year = abs ( intval ( $year ) );
 $month = abs ( intval ( $month ) );

 //是否是32位机
 if (is32())
 {
  if ($year = 2038)
  {
   $year = date ( 'Y' );
  }
 } else
 {
  if ($year   {
   $year = date ( 'Y' );
  }

 }

 if ($month 12)
 {
  $month = date ( 'm' );
 }

 //上一年
 $pretYear = $year - 1;
 //上一月
 $mpYear = $year;
 $preMonth = $month - 1;
 if ($preMonth  {
  $preMonth = 1;
  $mpYear = $pretYear;
 }

 //下一年
 $nextYear = $year + 1;
 //下一月
 $mnYear = $year;
 $nextMonth = $month + 1;
 if ($nextMonth > 12)
 {
  $nextMonth = 1;
  $mnYear = $nextYear;
 }

 //日历头
 $html =


 
   
   
    
   
 
 
 
   
 
 
   
 
上一年 上一月 回到今天 下一月 下一年
{$year}年{$month}月

  
   
    
    
    
    
    
    
    
   
HTML;

 $currentDay = date ( 'Y-m-j' );

 //当月最后一天
 $lastday = date ( 'j', mktime ( 0, 0, 0, $nextMonth, 0, $year ) );

 //循环输出天数
 $day = 1;
 $line = '';
 while ( $day  {
  $cday = $year . '-' . $month . '-' . $day;

  //当前星期几
  $nowWeek = date ( 'N', mktime ( 0, 0, 0, $month, $day, $year ) );

  if ($day == 1)
  {
   $line = '';
   $line .= str_repeat ( '', $nowWeek - 1 );
  }

  if ($cday == $currentDay)
  {
   $style = 'style="color:red;"';
  } else
  {
   $style = '';
  }

  $line .= "";

  //一周结束
  if ($nowWeek == 7)
  {
   $line .= '';
   $html .= $line;
   $line = '';
  }

  //全月结束
  if ($day == $lastday)
  {
   if ($nowWeek != 7)
   {
    $line .= str_repeat ( '', 7 - $nowWeek );
   }
   $line .= '';
   $html .= $line;

   break;
  }

  $day ++;
 }

 $html .=   
星期一 星期二 星期三 星期四 星期五 星期六 星期天
 $day
 
 
 

HTML;
 return $html;
}

/**
 *
 * 检测是否是32位机
 * @author fc_lamp
 * @blog: fc-lamp.blog.163.com
 */
function is32()
{
 $is32 = False;
 if (strtotime ( '2039-10-10' ) === False)
 {
  $is32 = True;
 }
 return $is32;
}

使用DateTime 类解决2038问题,这样不分32位与64位,代码如下:
