想要從兩個日期之間減去小時，分鐘到幾分鐘，秒到秒

Question

<?php 
    $ts='2011-04-13 23:00:00'; 
    $ts1='2011-04-14 15:45:00'; 
    echo $addtime = date("h:i:s", mktime(date("h", $ts1)- date("h", $ts),date("i", $ts1)- date("i", $ts),date("s", $ts1)- date("s", $ts),0,0,0)); 
?> 

它給出了一個結果，但在許多情況下它不正確。我如何解決它？

對於給定的例子，您的預期結果將是16:45:00，對吧？所以你需要以小時爲單位的兩個給定日期之間的差異：分鐘：秒。

<?php 
    //initial strings 
    $ts='2011-04-13 23:00:00'; 
    $ts1='2011-04-14 15:45:00'; 

    //converting to time 
    $start = strtotime($ts); 
    $end = strtotime($ts1); 

    //calculating the difference 
    $difference = $end - $start; 

    //calculating hours, minutes and seconds (as floating point values) 
    $hours = $difference/3600; //one hour has 3600 seconds 
    $minutes = ($hours - floor($hours)) * 60; 
    $seconds = ($minutes - floor($minutes)) * 60; 

    //formatting hours, minutes and seconds 
    $final_hours = floor($hours); 
    $final_minutes = floor($minutes); 
    $final_seconds = floor($seconds); 

    //output 
    echo $final_hours . ":" . $final_minutes . ":" . $final_seconds; 
?> 

這給了我正確的結果。希望我解決了你的問題！
