微信开发小结-PHP-php手册-php.cn

功能点：

1、网页授权获得微信用户信息

用户在微信客户端中访问第三方网页，公众号可以通过微信网页授权机制，来获取用户基本信息，进而实现业务逻辑。

注意点：Scope为snsapi_base 只能获得用户的openid,为snsapi_userinfo(会跳出一个授权页面)时可以获得openid,nicknam,sex,province等详见接口文档。

应用场景：第一次需要授权，后面无需授权。

解决方案，第一次为snsapi_userinfo，保存信息，非第一次去检查这个openid是否已存在如果不存在跳转至snsapi_userinfo的页面授权，否则就直接从读取信息。

2、分享接口

该接口较简单，引入js,按照官方文档说明就行

3、微信支付

开通微信支付功能，下载官方的Demo,lib/WxPay.Config.php 配置各个信息，证书位置建议使用绝对位置，防止被下载。
