php代码
<?php
session_start();
$nowtime = time() ;
if (session_is_registered('lasttime'))
{
$lasttime = $_SESSION['lasttime'];
$times = $_SESSION['times'] + 1;
$_SESSION['times'] = $times;
}else{
$lasttime = $nowtime;
$times = 1;
$_SESSION['times'] = $times;
$_SESSION['lasttime'] = $lasttime;
}
if (($nowtime - $lasttime)=5){
header(sprintf("Location: %s",'http://127.0.0.1'));
exit;
}
}else{
$times = 0;
$_SESSION['lasttime'] = $nowtime;
$_SESSION['times'] = $times;
}
?>
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
