给网站添加动态的运行天数统计代码

PHP版

<?php
// 设置时区
date_default_timezone_set('Asia/Shanghai');
function Sec2Time($time){
    if(is_numeric($time)){
        $value = array(
        "years" => 0, "days" => 0, "hours" => 0,
        "minutes" => 0, "seconds" => 0,
        );
        if($time >= 31556926){
            $value["years"] = floor($time/31556926);
            $time = ($time%31556926);
            }
        if($time >= 86400){
            $value["days"] = floor($time/86400);
            $time = ($time%86400);
        }
        if($time >= 3600){
            $value["hours"] = floor($time/3600);
            $time = ($time%3600);
        }
        if($time >= 60){
            $value["minutes"] = floor($time/60);
            $time = ($time%60);
        }
        $value["seconds"] = floor($time);
        return (array) $value;
    }else{
        return (bool) FALSE;
    }
}
// 本站创建的时间
$site_create_time = strtotime('2013-05-22 00:00:00');
$time = time() - $site_create_time;
$uptime = Sec2Time($time);
?>
本站运行：<span style="color:red;"><?php echo $uptime['years']; ?>年<?php echo $uptime['days']; ?>天<?php echo $uptime['hours']; ?>小时<?php echo $uptime['minutes']; ?>分<?php echo $uptime['seconds']; ?>秒</span>

JS版

<script type="text/javascript" language="javascript">

    // 博客创建时间秒数，时间格式中，月比较特殊，是从 0 开始的，所以想要显示 5 月，得写 4 才行，如下
    var create_time = Math.round(new Date(Date.UTC(2013, 4, 22, 0, 0, 0)).getTime() / 1000);
    // 当前时间秒数,增加时区的差异
