PHP calculates the difference between two times (seconds, minutes, hours, days, months, years)

Example code for the month difference between two times:

The code is as follows

$yourdate="2012-10- 20";
$yourdate_unix=strtotime($yourdate);
echo (date("Y",$yourdate_unix)-date("Y"))*12+(date("m",$yourdate_unix)-date("m"));

代码如下
$yourdate="2012-10-20"; $yourdate_unix=strtotime($yourdate); echo (date("Y",$yourdate_unix)-date("Y"))*12+(date("m",$yourdate_unix)-date("m"));

Example 1

The code is as follows

/*
* Calculate the month difference between two time periods
* @param $st start time $et end time (timestamp format)
* @return $total the difference returned
*/
function getMonthNum($st, $et)
{
$s_m = date('n', $st);
$e_m = date('n', $et);
$s_y = date('Y', $st);
$e_y = date('Y', $et);
$total = 13 - $s_m + ($e_y - $s_y - 1) * 12 + $e_m; //Calculate month difference
Return $total;
}

代码如下
/* * 计算2个时间段的月份差 * @param $st开始时间 $et结束时间(时间戳格式) * @return $total 返回的差值 / function getMonthNum($st, $et) { $s_m = date('n', $st); $e_m = date('n', $et); $s_y = date('Y', $st); $e_y = date('Y', $et); $total = 13 - $s_m + ($e_y - $s_y - 1) 12 + $e_m; //计算月份差 return $total; }

　　例子2

代码如下

$one = strtotime('2011-05-08 07:02:40');//开始时间时间戳
$tow = strtotime('2012-12-25 00:00:00');//结束时间时间戳
$cle = $tow - $one; //得出时间戳差值

代码如下

$one = strtotime('2011-05-08 07:02:40');//开始时间时间戳
$tow = strtotime('2012-12-25 00:00:00');//结束时间时间戳
$cle = $tow - $one; //得出时间戳差值

/* 这个只是提示
echo ceil($cle/60); //得出一共多少分钟
echo ceil($cle/3600); //得出一共多少小时
echo ceil($cle/3600/24); //得出一共多少天
*/
/*ceil()函数，即进一法取整*/
$d = cell($cle/3600/24);
$h = cell(($cle%(3600*24))/3600); //%取余
$m = cell(($cle%(3600*24))/60);

echo "两个时间相差 $d 天 $h 小时 $m 分"
?>

代码如下

/*
*
*函数功能：计算两个以YYYY-MM-DD为格式的日期，相差几天
*
*/
function getChaBetweenTwoDate($date1,$date2){

$Date_List_a1=explode("-",$date1);
$Date_List_a2=explode("-",$date2);

$d1=mktime(0,0,0,$Date_List_a1[1],$Date_List_a1[2],$Date_List_a1[0]);

$d2=mktime(0,0,0,$Date_List_a2[1],$Date_List_a2[2],$Date_List_a2[0]);

$Days=round(($d1-$d2)/3600/24);

return $Days;
}

echo getChaBetweenTwoDate('2010-08-11','2010-08-16');
echo "
";
echo getChaBetweenTwoDate('2010-08-16','2010-08-11');
?>

　　例子3

代码如下

/*
*
*函数功能：计算两个以YYYY-MM-DD为格式的日期，相差几天
*
*/
function getChaBetweenTwoDate($date1,$date2){<🎜>

$Date_List_a1=explode("-",$date1);
$Date_List_a2=explode("-",$date2);<🎜>

$d1=mktime(0,0,0,$Date_List_a1[1],$Date_List_a1[2],$Date_List_a1[0]);<🎜>

$d2=mktime(0,0,0,$Date_List_a2[1],$Date_List_a2[2],$Date_List_a2[0]);<🎜>

$Days=round(($d1-$d2)/3600/24);<🎜>

return $Days;
}<🎜>

echo getChaBetweenTwoDate('2010-08-11','2010-08-16');
echo "
";
echo getChaBetweenTwoDate('2010-08-16','2010-08-11');
?>

　　例子4

代码如下

$startdate=”2010-12-11 11:40:00″;
$enddate=”2012-12-12 11:45:09″;
$date=floor((strtotime($enddate)-strtotime($startdate))/86400);
$hour=floor((strtotime($enddate)-strtotime($startdate))%86400/3600);
$minute=floor((strtotime($enddate)-strtotime($startdate))%86400/60);
$second=floor((strtotime($enddate)-strtotime($startdate))%86400%60);
echo $date.”天
”;
echo $hour.”小时
”;
echo $minute.”分钟
”;
echo $second.”秒
”;
?>

代码如下

　　例子四是我最喜欢的一个可以计算到天小时秒哦，当然具体的还是需要根据自己的需要了。
