phpcookie类

1.需求

写一个cookie类

2.例子

<?php

class cookie{
    private $COOKIE_PREFIX = "";
    private $COOKIE_EXPIRE = "";
    private $COOKIE_PATH = "";
    private $COOKIE_DOMAIN = "";

    public function __construct()
    {
        //这里要加载config并赋值cookie的相关参数
    }

    public function set_prefix($prefix='')
    {
        $this->COOKIE_PREFIX=$prefix;
    }

    public function get_prefix()
    {
        return $this->COOKIE_PREFIX;
    }

    public function is_set_cookies($name)
    {
        return isset($_COOKIE[$this->COOKIE_PREFIX . $name]);
    }

    public function get_cookie($name)
    {
        //正式环境下，这里要解密cookie
        $value = $_COOKIE[$this->COOKIE_PREFIX . $name];
        return $value;
    }

    public function set_cookie($name, $value, $expire = "", $PATH = "", $domain = "", $prefix = "")
    {
        if (empty($expire))
        {
            $expire = $this->COOKIE_EXPIRE;
        }
        else
        {
            $expire = time()+$expire;
        }
        if (empty($path)) {
            $path = $this->COOKIE_PATH;
        }

        if (empty($domain)) {
            $domain = $this->COOKIE_DOMAIN;
        }

        if (empty($prefix)) {
            $prefix = $this->COOKIE_PREFIX;
        }
        //value要加密
        setcookie($prefix . $name, $value, $expire, $path, $domain, NULL, true);
        $_COOKIE[$prefix . $name] = $value;
    }

    public function delete_cookie($name)
    {
        setcookie($name,'',-1);
        $_COOKIE[$this->COOKIE_PREFIX . $name]=null;
        unset($_COOKIE[$this->COOKIE_PREFIX . $name]);
    }
    public function clear_all_cookie()
    {
        $_COOKIE =array();
        unset($_COOKIE);
    }
}

3.待完善部分

cookie的设置和读取要加密和解密的过程。
