PHP实现显示网站运行时间

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

如果你想计算多少年多少月多少日可用下面代码实现：

<?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';
  }
}
?>

本站运行：4年8月3天
