把秒转换成天数，小时数和分钟
[code lang=”php”]
function secsToStr($secs) {
if($secs>=86400){$days=floor($secs/86400);$secs=$secs%86400;$r=$days.’ day’;if($days<>1){$r.=’s’;}if($secs>0){$r.=’, ‘;}}
if($secs>=3600){$hours=floor($secs/3600);$secs=$secs%3600;$r.=$hours.’ hour’;if($hours<>1){$r.=’s’;}if($secs>0){$r.=’, ‘;}}
if($secs>=60){$minutes=floor($secs/60);$secs=$secs%60;$r.=$minutes.’ minute’;if($minutes<>1){$r.=’s’;}if($secs>0){$r.=’, ‘;}}
$r.=$secs.’ second’;if($secs<>1){$r.=’s’;}
return $r;
}
