1.初始化数据库

我用的是新浪SAE上的MYSQL。

官方文档:https://www.sinacloud.com/doc/sae/php/mysql.html#api-shi-yong-shou-ce

2.查询语句

链接数据库:(SAE提供了基于MYSQL模块的SaeMysql类)

$mysql = new SaeMysql();

直接实例化即完成链接操作,无须进行其他操作。

例如:

增加数据:(注意weixin附近的不是单引号,是TAB键上面那个键的值)

$mysql = new SaeMysql();

$sql = "insert into `weixin`(`id`,`title`,`content`) values(null,"haha",:"gaga")";

3.公众号关键词查询

4.识别新老用户

     手机微信客户端传输到微信公众账号的用户信息为加密的openid,保存在变量$fromUsername中,我们可以将$fromUsername保存到数据库中,从而实现CRM(客户关系管理)。

新建数据表crm:

<span style="color: #008080;">1</span> <span style="color: #0000ff;">CREATE</span> <span style="color: #0000ff;">TABLE</span><span style="color: #000000;">  `app_landiljy`.`crm` (
</span><span style="color: #008080;">2</span> `id` <span style="color: #0000ff;">INT</span> <span style="color: #808080;">NOT</span> <span style="color: #0000ff;">NULL</span><span style="color: #000000;"> AUTO_INCREMENT ,
</span><span style="color: #008080;">3</span> `<span style="color: #ff00ff;">user</span>` <span style="color: #0000ff;">VARCHAR</span>( <span style="color: #800000; font-weight: bold;">255</span> ) <span style="color: #0000ff;">CHARACTER</span> <span style="color: #0000ff;">SET</span> utf8 COLLATE utf8_general_ci <span style="color: #808080;">NOT</span> <span style="color: #0000ff;">NULL</span><span style="color: #000000;"> ,
</span><span style="color: #008080;">4</span> <span style="color: #0000ff;">PRIMARY</span> <span style="color: #0000ff;">KEY</span><span style="color: #000000;"> (  `id` )
</span><span style="color: #008080;">5</span> ) ENGINE <span style="color: #808080;">=</span> INNODB;

先判断是新客户还是老客户,当新客户发送“你好”时,回复“欢迎新朋友”;当老客户发送“你好”时,回复“欢迎老朋友”。
