就是一段小代码段，新手可参考参考。

<?php
$password = "yige.org"; // 这里是密码
$p = "";
if(isset($_COOKIE["isview"]) and $_COOKIE["isview"] == $password){
	$isview = true;
}else{
	if(isset($_POST["pwd"])){
		if($_POST["pwd"] == $password){
			setcookie("isview",$_POST["pwd"],time()+3600*3);
			$isview = true;
		}else{
			$p = (empty($_POST["pwd"])) ? "需要密码才能查看，请输入密码。" : "密码不正确，请重新输入。";
		}
	}else{
		$isview = false;
		$p = "请输入密码查看，获取密码可联系我。";
	}
}

if($isview){ ?> 

这里是密码成功后显示的地方
