php篇二 之微信公众号开发
php开发微信公众号
博主提示玩微信公众号必须要有自己的服务器，其次有自己的微信公众平台，将自己的token保存在开发者模式中，将代码上传到服务器中，并且保存在开发者模式中。代码类似如下
<?php
/**
* wechat php test
*/
//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->responseMsg();
//$wechatObj->valid();
class wechatCallbackapiTest
{
/*public function valid()
{
$echoStr = $_GET["echostr"];
//valid signature , option
if($this->checkSignature()){
echo $echoStr;
exit;
}
}*/
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);
$RX_TYPE = trim($postObj->MsgType);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "<xml>
