function daysInSpan($start,$end){
$dayTicks=ticksInDay();
return ($end-$start)/$dayTicks;
}

function ticksInDay(){
$today=getdate();
$yesterday=mktime(0,0,0,$today[mon],$today[mday]-1,$today[year]);
$today=mktime(0,0,0,$today[mon],$today[mday],$today[year]);
return $today-$yesterday;
}

function day($dayone,$daytwo){
$start_time_array=explode("/",$dayone);
$endtime_time_array=explode("/",$daytwo);

$start_time_year=$start_time_array[0];
$start_time_month=$start_time_array[1];
$start_time_day=$start_time_array[2];

$end_time_year=$endtime_time_array[0];
$end_time_month=$endtime_time_array[1];
$end_time_day=$endtime_time_array[2];

return daysInSpan(mktime(0,0,0,$start_time_month,$start_time_day,0+$start_time_year),mktime(0,0,0,$end_time_month,$end_time_day,0+$end_time_year)); 
}

求教，上面的function怎么写成一个可以调用的类啊？
class seday{

}

调用：
import("seday.php");
$seday = new seday;
$dayCount = $seday->day("2009/02/23","2009/04/23");
dump($dayCount);

class seday{

function daysInSpan($start,$end){
$dayTicks=$this->ticksInDay();
return ($end-$start)/$dayTicks;
}

function ticksInDay(){
$today=getdate();
$yesterday=mktime(0,0,0,$today[mon],$today[mday]-1,$today[year]);
$today=mktime(0,0,0,$today[mon],$today[mday],$today[year]);
return $today-$yesterday;
}

function day($dayone,$daytwo){
$start_time_array=explode("/",$dayone);
$endtime_time_array=explode("/",$daytwo);

$start_time_year=$start_time_array[0];
$start_time_month=$start_time_array[1];
$start_time_day=$start_time_array[2];

$end_time_year=$endtime_time_array[0];
$end_time_month=$endtime_time_array[1];
$end_time_day=$endtime_time_array[2];

return $this->daysInSpan(mktime(0,0,0,$start_time_month,$start_time_day,0+$start_time_year),
mktime(0,0,0,$end_time_month,$end_time_day,0+$end_time_year)
);
}

}

恩，解决了，开始我也在这里return $this->daysInSpan(mktime......加了$this->,但没看到$dayTicks=$this->ticksInDay();就老是报错，呵呵。这里也调用了其他方法，其实构造类的时候，在类的内部调用function时，要$this->函数名，是吧？

老大把这个帖子删掉吧，我在“扩展代码分享”板块发了个贴“  php计算两个时间差的类 ”，是把改好了的发上去的
