php实例分享之实现显示网站运行时间

废话不多说，直接上代码。

复制代码 代码如下:
<?php
// 设置时区
date_default_timezone_set('Asia/Shanghai');
/**
 * 秒转时间，格式 年 月 日 时 分 秒
 *
 * @author wangyupeng129@126.com
 * @param int $time
 * @return array|boolean
 */
function Sec2Time($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>
