网站已运行时间代码

新搭建的Wordpress网站想要在页脚加上一个网站已运行时间的文字

在页脚（footer.php）添加以下代码

<?php 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('2017-03-26 11:40:00');
$time = time() - $site_create_time;
$uptime = Sec2Time($time);
?>

本站运行：<a><?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  </a>

但此方式时间不会动态变化，于是采用Js实现：

<script language=javascript>
function siteTime(){
window.setTimeout("siteTime()", 1000);
var seconds = 1000
var minutes = seconds * 60
var hours = minutes * 60
var days = hours * 24
var years = days * 365

var today = new Date()
var todayYear = today.getFullYear()
var todayMonth = today.getMonth()
var todayDate = today.getDate()
var todayHour = today.getHours()
var todayMinute = today.getMinutes()
var todaySecond = today.getSeconds()

/* Date.UTC() -- 返回date对象距世界标准时间(UTC)1970年1月1日午夜之间的毫秒数(时间戳) 
year - 作为date对象的年份，为4位年份值
month - 0-11之间的整数，做为date对象的月份
day - 1-31之间的整数，做为date对象的天数
hours - 0(午夜24点)-23之间的整数，做为date对象的小时数
minutes - 0-59之间的整数，做为date对象的分钟数
seconds - 0-59之间的整数，做为date对象的秒数
microseconds - 0-999之间的整数，做为date对象的毫秒数 */
var t1 = Date.UTC(2014,0,14,11,19,00)
var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond)
var diff = t2-t1

var diffYears = Math.floor(diff/years)
var diffDays = Math.floor((diff/days)-diffYears*365)
var diffHours = Math.floor((diff-(diffYears*365+diffDays)*days)/hours)
var diffMinutes = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours)/minutes)
var diffSeconds = Math.floor((diff-(diffYears*365+diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds)
document.getElementById("sitetime").innerHTML=" 已运行"+diffYears+" 年 "+diffDays+" 天 "+diffHours+" 小时 "+diffMinutes+" 分钟 "+diffSeconds+" 秒"
}
siteTime()
</script>

<a id="sitetime"></a>
