The implementation of PHP instance sharing displays the running time of the website

Without further ado, go straight to the code.

<?php
//Set the time zone
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;
 }
}
//Site creation time
$site_create_time = strtotime('2013-05-22 00:00:00');
$time = time() - $site_create_time;
$uptime = Sec2Time($time);
?>

This site runs: < Span style = "color: red;" > < ? PHP echo $uptime [' years']; ? > Years < ? PHP echo $uptime [' days']; ? > Day < ? PHP echo $uptime [' hours']; ? > Hours < ? PHP echo $uptime [' minutes']; ? > Points < ? PHP echo $uptime [' seconds']; ? > Seconds < / span>
