javascriptfunction secsToStr($secs) { if ($secs==86400) { $days=floor($secs / 86400); $secs %=86400; $r=$days + '天'; } if ($secs==3600) { $hours=floor($secs / 3600); $secs %=3600; $r=$hours + '小时'; }}

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; }
用法：

<?php $seconds = "56789"; $output = secsToStr($seconds); echo $output; ?>
