这篇文章主要介绍了微信公众平台DEMO(PHP),需要的朋友可以参考下
本人在SAE环境下搭建了CI框架(其实这个小东西用不着用框架的)，直接把代码写在了控制器里面
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
//define your token
define("TOKEN", "109");
class Welcome extends CI_Controller {
public function index()
{
/*
$this->load->helper('url');
$this->load->view('welcome_message');
*/
// use chat response
$this->responseMsg();
}
// chat response
public function responseMsg()
{
//get post data, May be due to the different environments
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$MsgType = $postObj->MsgType;
$time = time();
switch($MsgType){
case('text'):
$keyword = trim($postObj->Content);

// random read data from jokes
$sql = 'SELECT * FROM jokes';

$key = rand(0, $num_rows - 1); // Notice: The value of key is from 0.
