Php将秒转换为只读值的可读格式

Question

我在下面有这个功能。

function secondsToTime($seconds) { 
    $dtF = new DateTime("@0"); 
    $dtT = new DateTime("@$seconds"); 
    return $dtF->diff($dtT)->format('%a days, %h hours, %i minutes and %s seconds'); 
} 

以上下面

0 days, 0 hours, 2 minutes and 52 seconds 

功能例如172秒回报，但我希望它是只

2 minutes and 52 seconds 

，或者如果其小于60秒其应该忽略分钟..

Answer 1

$seconds=172; 
function sec_to_time($seconds) { 
$hours = floor($seconds/3600); 
$minutes = floor($seconds % 3600/60); 
$seconds = $seconds % 60; 
if($hours>0) 
{ 
    return sprintf(" %d hours %02d , minutes %02d , seconds", $hours, $minutes, $seconds); 
} 
else if($minutes>0) 
{ 
    return sprintf("%02d minutes , %02d seconds", $minutes, $seconds); 
} 
else 
{ 
    return sprintf("%02d seconds", $seconds); 
} 
} 
echo sec_to_time($seconds); 

或新的答案，因为你更新功能

function secondsToTime($seconds) { 
    $dtF = new DateTime("@0"); 
    $dtT = new DateTime("@$seconds"); 
    $a=$dtF->diff($dtT)->format('%a'); 
    $h=$dtF->diff($dtT)->format('%h'); 
    $i=$dtF->diff($dtT)->format('%i'); 
    $s=$dtF->diff($dtT)->format('%s'); 
    if($a>0) 
    { 
     return $dtF->diff($dtT)->format('%a days, %h hours, %i minutes and %s seconds'); 
    } 
    else if($h>0) 
    { 
     return $dtF->diff($dtT)->format('%h hours, %i minutes and %s seconds'); 
    } 
    else if($i>0) 
    { 
     return $dtF->diff($dtT)->format(' %i minutes and %s seconds'); 
    } 
    else 
    { 
     return $dtF->diff($dtT)->format('%s seconds'); 
    } 
} 
echo secondsToTime(172);
