PHP 秒数转换成时分秒的格式

**代码中引用的php函数
sprintff—返回一个格式化的字符串
intval — 获取变量的整数值

如果可以的话，看到这篇博文的朋友 可以加我的扣扣大家一起交流
扣扣:354-032-267。家相互学习，

<?php 

secondsToHour("传入要转换的秒数");

function secondsToHour($seconds){
   if(intval($seconds) < 60)
        $tt ="00:00:".sprintf("%02d",intval($seconds%60));
   if(intval($seconds) >=60){
        $h =sprintf("%02d",intval($seconds/60));
        $s =sprintf("%02d",intval($seconds%60));
        if($s == 60){
            $s = sprintf("%02d",0);
            ++$h;
        }
        $t = "00";
       if($h == 60){
            $h = sprintf("%02d",0);
            ++$t;
       }
       if($t){
