php calender(日历)二个版本代码示例(解决2038问题)

导读：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) 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

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)

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 < 1970 or $year >= 2038)
{
$year = date ( 'Y' );
}
} else
{
if ($year <= 0)
{
$year = date ( 'Y' );
}}if ($month <= 0 or $month > 12)
{
$month = date ( 'm' );
}//上一年
$pretYear = $year - 1;
//上一月
$mpYear = $year;
$preMonth = $month - 1;
if ($preMonth <= 0)
{
$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 = <<

$line .= str_repeat ( '}if ($cday == $currentDay)
{
$style = 'style="color:red;"';
} else
{
$style = '';
}$line .= "}//全月结束
if ($day == $lastday)
{
if ($nowWeek != 7)
{
$line .= str_repeat ( '}
$line .= '$html .= $line;break;
}$day ++;
}$html .= << 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：

代码如下:

/**
* 
* 我的日历(DateTime版本)
* 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 = '',$timezone = 'Asia/Shanghai')
{date_default_timezone_set ( $timezone );
$year = abs ( intval ( $year ) );
$month = abs ( intval ( $month ) );$nowDate = new DateTime();if ($year <= 0)
{
$year = $nowDate->format( 'Y' );
}if ($month <= 0 or $month > 12)
{
$month = $nowDate->format('m' );
}//上一年
$pretYear = $year - 1;
//上一月
$mpYear = $year;
$preMonth = $month - 1;
if ($preMonth <= 0)
{
$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 = <<

						HTML;$currentDay = date ( 'Y-m-j' );//当月最后一天 $lastday = date ( 'j',mktime ( 0,$nextMonth,$year ) );//循环输出天数 $day = 1; $line = ''; while ( $day <= $lastday ) { $cday = $year . '-' . $month . '-' . $day;//当前星期几 $nowWeek = date ( 'N',$month,$day,$year ) );if ($day == 1) { $line = '
$dayif ($nowWeek == 7) { $line .= '$html .= $line; $line = '

$line .= str_repeat ( '}
$line .= '$html .= $line;break;
}$day ++;
}$html .= << HTML;
return $html;
}
