代码实现输入密码才能浏览网页


效果演示图:

<?php
error_reporting(0); 
$pass= $_POST;
$sj = rand(123,999);
if (empty($_COOKIE["pass"])) {
	setcookie("pass",$sj, time()+86400);
	echo "<script language='JavaScript'> 
function myrefresh() 
{ 
window.location.reload(); 
} 
setTimeout('myrefresh()',10); //指定1秒刷新一次 
</script>";
}
if($_COOKIE["zt"]!=="ok"){
      if($pass[pass]=="" || $pass[pass]!=$_COOKIE["pass"]) {
echo '
