Question

在我的PHP应用程序中，我想计算两个时间变量的总和。我正在寻找类似这样的例子。

$time1 = 15:20:00;
$time2 = 00:30:00;
$time = $time1+$time2;

Answer 1

如果您期望的答案是15:50:00，并且您想要使用strtotime和date函数，则需要减去秒$time1和$time2份额当你将它们转换为unix时间戳时：

$time1 = '15:20:00';
$time2 = '00:30:00';
$time = strtotime($time1) + strtotime($time2) - strtotime('00:00:00');
$time = date('H:i:s', $time);

Answer 2

以下答案未返回正确的值。它是求和整数但没有返回正确的时间。

$ o = strtotime（$ time1）+ strtotime（$ time2）;

我创建了一个函数来获得如下计算时间。

public function addTwoTimes($time1 = "00:00:00", $time2 = "00:00:00"){
        $time2_arr = [];
        $time1 = $time1;
        $time2_arr = explode(":", $time2);
        //Hour
        if(isset($time2_arr[0]) && $time2_arr[0] != ""){
            $time1 = $time1." +".$time2_arr[0]." hours";
            $time1 = date("H:i:s", strtotime($time1));
        }
        //Minutes
        if(isset($time2_arr[1]) && $time2_arr[1] != ""){
            $time1 = $time1." +".$time2_arr[1]." minutes";
            $time1 = date("H:i:s", strtotime($time1));
        }
        //Seconds
        if(isset($time2_arr[2]) && $time2_arr[2] != ""){
            $time1 = $time1." +".$time2_arr[2]." seconds";
            $time1 = date("H:i:s", strtotime($time1));
        }

        return date("H:i:s", strtotime($time1));
    }

Answer 3

最好的方法是使用strtotime将它们转换为时间戳，然后再一起添加：

$o = strtotime($time1)+strtotime($time2);

如果我没记错，strtotime确实支持这种格式。

否则你需要自己过滤掉它。

Answer 4

您可以使用PHP 5.3 DateInterval：

$timeInterval = DateInterval::createFromDateString( '15 hours + 20 minutes' );
$timeInterval2 = DateInterval::createFromDateString( '30 minutes' );

foreach( str_split( 'ymdhis' ) as $prop )
{
    $timeInterval->$prop += $timeInterval2->$prop;
}
var_dump( $timeInterval->format( '%H:%i:%s' ) );

（这里解释了如何添加到DateInterval对象：How we can add two date intervals in PHP）

Answer 5

据我所知，Sammaye的答案对我没有用。

我需要在UNIX时间戳的开头添加我想要添加的时间。这样，strtotime将返回第一次需要添加的秒数。

$time1 = "15:20:00";
$time2 = "1970-01-01 00:30:00";
$time = strtotime($time1) + (strtotime($time2) + 3600);
echo $time . "<br />";
echo date("H:i:s", $time);

Answer 6

请务必参考神秘博士http://us1.php.net/strtotime，了解您可以输入功能的其他内容：）

$today = time();
$tommorrow = strtotime("+1 days", $today);
$day_after_tomorrow = strtotime("+1 days", $tomorrow);

Answer 7

<强>代码：

$time1 = '15:20:00';
$time2 = '00:30:00';
$time = strtotime($time1)+strtotime($time2);
$sumtime = date("H:i:s",$time);

PHP加起来两个时间变量
