PHP计算总时间

Question

如何编写计算总工作时间的PHP代码？

例如：

工作时间开始：$starttime = 10:20
工作时间结束：“$stoptime = 12:59

总工作时间：$totaltime应为：02:39

Answer 1

使用此

<?php
$start = strtotime("12/12/2012 10:20:00"); 

$end = strtotime("12/12/2012 12:59:00"); 

$totaltime = ($end - $start)  ; 

$hours = intval($totaltime / 3600);   
$seconds_remain = ($totaltime - ($hours * 3600)); 

$minutes = intval($seconds_remain / 60);   
$seconds = ($seconds_remain - ($minutes * 60)); 

echo "$hours:$minutes:$seconds"; 
?>

Answer 2

试试这段代码。

    $starttime = '10:20';
    $stoptime = '12:59';
    $diff = (strtotime($stoptime) - strtotime($starttime));
    $total = $diff/60;
    echo sprintf("%02dh %02dm", floor($total/60), $total%60);
