微信公众平台开发（四）简单回复功能开发

来源：http://www.cnblogs.com/mchina/p/3155072.html<div> </div><div>一、简介微信公众平台可以根据用户发送的信息进行判断，然后给出对应的回复，具有良好的交互性。下文将模拟简单的回复功能，根据这个案例，开发者也可以基本理解微信交互的原理，进行更深层次的开发。二、思路分析用户发送过来的文本信息，我们可以提取关键字，通过简单的 if...elseif...else... 实现。关键代码如下：<div class="cnblogs_code" style="margin-top: 5px; margin-bottom: 5px; padding: 5px; border: 1px solid rgb(204, 204, 204); overflow: auto; color: rgb(0, 0, 0); font-family: "Courier New" !important; font-size: 12px !important; background-color: rgb(245, 245, 245);"><div class="cnblogs_code_toolbar" style="margin-top: 5px;"><a title="复制代码" style="color: rgb(0, 0, 0); border: none !important;"><img src="http://common.cnblogs.com/images/copycode.gif" alt="复制代码" style="max-width: 900px;"></a></div><pre style="white-space: pre-wrap; font-family: "Courier New" !important;">if($keyword=="你好"){
　　$contentStr = "hello";
}elseif($keyword=="苏州"){
　　$contentStr = "上有天堂，下有苏杭";
}else{
　　$contentStr = "感谢您关注【卓锦苏州】微信号：zhuojinsz";
}</pre><div class="cnblogs_code_toolbar" style="margin-top: 5px;"><a title="复制代码" style="color: rgb(0, 0, 0); border: none !important;"><img src="http://common.cnblogs.com/images/copycode.gif" alt="复制代码" style="max-width: 900px;"></a></div></div>如果用户发送"你好"，则回复"hello"，如果用户发送"苏州"，则回复"上有天堂，下有苏杭"，其他信息，则回复你的欢迎词。三、完整代码<div class="cnblogs_code" style="margin-top: 5px; margin-bottom: 5px; padding: 5px; border: 1px solid rgb(204, 204, 204); overflow: auto; color: rgb(0, 0, 0); font-family: "Courier New" !important; font-size: 12px !important; background-color: rgb(245, 245, 245);"><div class="cnblogs_code_toolbar" style="margin-top: 5px;"><a title="复制代码" style="color: rgb(0, 0, 0); border: none !important;"><img src="http://common.cnblogs.com/images/copycode.gif" alt="复制代码" style="max-width: 900px;"></a></div><pre style="white-space: pre-wrap; font-family: "Courier New" !important;"><?php
