自定义方法search

 - function search($a){
 - ····
 -  return $b
 - }
 - $rs = search($keyword);

核心代码如下：

function chaxun($a){
        //用 户 名 :  $user
        //密　　码 :  $pwd
        //主库域名 :  $host
        //从库域名 :  SAE_MYSQL_HOST_S
        //端　　口 :  $port
        //数据库名 :  $dbname

        $dbname = "app_dq095";
        $host = "w.rdc.sae.sina.com.cn";
        $port = "3306";
        $user = "4k514n103z";
        $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203";

        /*接着调用mysql_connect()连接服务器*/
        // 连主库
        $db = mysql_connect($host,$user,$pwd);

        if(!$db){
            die("Connect Server Failed: " . mysql_error($db));
        }

        /*连接成功后立即调用mysql_select_db()选中需要连接的数据库*/
        if (!mysql_select_db($dbname)) {
            die("Select Database Failed: " . mysql_error($db));
        }
        mysql_query("set names utf-8",$db); 

        /*至此连接已完全建立，就可对当前数据库进行相应的操作了*/      
        /**
          * 接下来就可以使用其它标准php mysql函数操作进行数据库操作
        */

        mysql_query("set names utf-8",$link); 

        $sql="SELECT `DQ` FROM `shen` WHERE `BM`='" . iconv("UTF-8","GBK",$a) . "'";
        $query=mysql_query($sql);
        $rs=mysql_fetch_array($query);
        $c= $rs['DQ'];
        $b=iconv("GBK","UTF-8",$c);
        if (empty($b)){
            $c="对不起,暂无此数据";
        }
        return $c;
        mysql_close($db);
}

//define your token
define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->responseMsg();

调用方法如下：

 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
  $fromUsername = $postObj->FromUserName;
  $toUsername = $postObj->ToUserName;
  $keyword = trim($postObj->Content);
  $time = time();
  $textTpl = "<xml>
              <ToUserName>ToUserName>
              <FromUserName>FromUserName>
              <CreateTime>%sCreateTime>
              <MsgType>MsgType>
              <Content>Content>
              <FuncFlag>0FuncFlag>
              xml>";   

 if(!empty($keyword ))
{
$msgType = "text";
$contentStr= chaxun($keyword);

$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
    echo $resultStr;

 }else{
    echo "Input something...";
 }
