太简单了，但时间长了，记不得，浪费我半小时找资料，深刻体会好记性不如烂笔头！！今天把passport文挡贴上，防止以后忘记！！记住，网上找到自己需要的资料也要耗时间的!!!!!!

Passport 通行证整合第一篇：整合原理

请注意: 整合不成功可能造成的后果-----dz论坛无法登录,无法管理
解决办法:
第一步: 到dz的数据库表cdb_settings 找到下面这几行修改为

setting.gif (4.3 KB)

2006-9-30 13:59

第二步: 删除dz安装目录/forumdata/cache/cache_settings.php
第三步: 重新访问论坛

登陆和注册整合流程
用户从登陆或注册表单提交帐号密码信息 ==>
主站程序检验用户登陆或注册,成功(注册需要生成新用户)则 ==>
设置主站自身的cookie或session ==>
url传递返回地址forward和编码后的用户信息和其他信息到dz/api/passport.php

整合之前请先仔细阅读官方passport技术文档: http://www.discuz.net/usersguide/advanced_passport.htm

复制内容到剪贴板代码:<?php
//该文档保存为login.php
//首先将接口技术文档里的加密解密函数拷贝
//为了不让代码太乱，我拷贝到文档的结尾处
//假设自己的用户数据库表里用户名字段为UserName, 密码字段为Pwd, Email字段为 Email
//注册页实现方法差不多，可自行实现，疑问加我QQ:2666556

$act=(isset($_GET['act']))?$_GET['act']:"login";
if(function_exists($act)) $act();else login();

function login()
{
$ErrMsg=UserCheck();
if($ErrMsg!="")echo $ErrMsg;
//后面加上显示你的登陆表单的代码如
?>
<form action=login.php?act=login method=post>
用户名:<input name=username>
密码:<input name=password>
<input name=submit type=submit value=登陆></form>

[2]php下检测字符串是否是utf8编码的代码

来源: 互联网发布时间: 2013-11-30

function is_utf8($string) {
     return preg_match('%^(?:
             [\x09\x0A\x0D\x20-\x7E]                 # ASCII
         | [\xC2-\xDF][\x80-\xBF]                 # non-overlong 2-byte
         |     \xE0[\xA0-\xBF][\x80-\xBF]             # excluding overlongs
         | [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2}     # straight 3-byte
         |     \xED[\x80-\x9F][\x80-\xBF]             # excluding surrogates
         |     \xF0[\x90-\xBF][\x80-\xBF]{2}     # planes 1-3
         | [\xF1-\xF3][\x80-\xBF]{3}             # planes 4-15
         |     \xF4[\x80-\x8F][\x80-\xBF]{2}     # plane 16
     )*$%xs', $string);
}
准确率基本和mb_detect_encoding一样，要对一起对，要错一起错。
编码检测不可能100%准确，这个东西已经可以基本满足要求了。
