如何將HH：MM：SS時間轉換爲天數：HH：MM：SS in php

Question

我需要將時間28:10:10（在HH：MM：SS中）轉換爲1:04:10:10 （日：HH：MM：SS）。我想使用apply strtime（）函數將輸入時間轉換爲24小時時間格式。

此外，我需要從它減去給定的時間。

**I have tried to answer your question. below is the code that will give you correct output. pls have a look on the below code.** 

function secondsToTime($ss) { 
     $s = $ss%60; 
     $m = floor(($ss%3600)/60); 
     $h = floor(($ss%86400)/3600); 
     $d = floor(($ss%2592000)/86400); 

     // Ensure all values are 2 digits, prepending zero if necessary. 
     $s = $s < 10 ? '0' . $s : $s; 
     $m = $m < 10 ? '0' . $m : $m; 
     $h = $h < 10 ? '0' . $h : $h; 
     $d = $d < 10 ? '0' . $d : $d; 

     return "$d:$h:$m:$s"; 
    } 



    $time = "28:10:10"; 
    $timeArr = array_reverse(explode(":", $time)); 
    $seconds = 0; 
    foreach ($timeArr as $key => $value) 
    { 
     if ($key > 2) break; 
     $seconds += pow(60, $key) * $value; 
    } 
    $seconds; 

    print secondsToTime($seconds); 

OUTPUT 1:04:10:10
