这里用的宝塔服务
创建域名绑定到指定的目录

wx.php 代码如下

<?php    
/**   * wechat php test   */    //define your token    
define("TOKEN", "weixin");    
$wechatObj = new wechatCallbackapiTest();    
$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);    $fromUsername = $postObj->FromUserName;    $toUsername = $postObj->ToUserName;    $keyword = trim($postObj->Content);    $time = time();    $textTpl = "<xml>    <ToUserName><![CDATA[%s]]></ToUserName>    <FromUserName><![CDATA[%s]]></FromUserName>    <CreateTime>%s</CreateTime>    <MsgType><![CDATA[%s]]></MsgType>    <Content><![CDATA[%s]]></Content>    <FuncFlag>0</FuncFlag>    </xml>";                 if(!empty( $keyword ))    {    $msgType = "text";    $contentStr = "Welcome to wechat world!";    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);    echo $resultStr;    }else{    echo "Input something...";    }    }else {    echo "";    exit;    }    }    private function checkSignature()    {    $signature = $_GET["signature"];    $timestamp = $_GET["timestamp"];    $nonce = $_GET["nonce"];        $token = TOKEN;    $tmpArr = array($token, $timestamp, $nonce);    sort($tmpArr);    $tmpStr = implode( $tmpArr );    $tmpStr = sha1( $tmpStr );    if( $tmpStr == $signature ){    return true;    }else{    return false;    }    }    
}    ?>

其中

define("TOKEN", "weixin");

第7行是用户定义的“token”，需要与下面将会提及的令牌(Token)相同。
