PHP实现显示网站运行时间 - 秒转换年月日时分秒

这篇文章主要介绍了php实现显示网站运行时间，需要的朋友可以参考下，假设你的当前时间为这种格式“2017-01-01”，想计算几天后时间格式，可用的计算代码如下：

本站运行：<?php echo floor((time()-strtotime('2017-01-01'))/86400);?>

本站运行：1704天

<?php
date_default_timezone_set('Asia/Shanghai');
function Sec2Time($time){if(is_numeric($time)){$value = array("y"=>0,"m" =>0,"d" =>0,"h" =>0,"i" =>0,"s" =>0,);
if($time>=31556926){$value["y"] = floor($time/31556926);$time=($time%31556926);}
if($time>=2592000){$value["m"]=floor($time/2592000);$time=($time%2592000);}
if($time>=86400){$value["d"]=floor($time/86400);$time=($time%86400);}
if($time>=3600){$value["h"]=floor($time/3600);$time = ($time%3600);}
if($time>=60){$value["i"] = floor($time/60);$time = ($time%60);}
$value["seconds"]=floor($time);return (array) $value;}else{return (bool) FALSE;}}
$site_create_time = strtotime('2017-01-01');
$time = time() - $site_create_time;
$sltime = Sec2Time($time);
echo '本站运行：';if($sltime['y']!='0'){echo $sltime['y'].'年';}if($sltime['m']=='0' && $sltime['d']=='0'){echo '整';}if($sltime['m']!='0'){echo $sltime['m'].'月';}else{if($sltime['d']!='0'){echo '零';}}if($sltime['d']!='0'){echo $sltime['d'].'天';}?>

输出格式为：

本站运行：4年8月3天
