php 利用cookie实现访问次数统计

<?php

global $count;

$count=1;

if(!isset($_COOKIE["visittime"])){ setcookie("visittime",date("y-m-d H:i:s"));

setcookie("visitcount",1); echo "欢迎你第一次访问网站!";

}

else{

setcookie("visittime",date("y-m-d,H:i:s"),time()+60); $count=$_COOKIE['visitcount']+1;

setcookie("visitcount",$count); echo "你上次访问网站的时间为:".$_COOKIE['visittime'];

echo "<br>";

}

echo "你第".$_COOKIE['visitcount']."访问网站的时间为:".date("y-m-d H:i:s");

?>
