這篇文章主要為大家詳細(xì)介紹了php微信公眾號開發(fā)之歡迎老朋友，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了php微信公眾號開發(fā)之歡迎老朋友的具體代碼，供大家參考，具體內(nèi)容如下

介紹數(shù)據(jù)庫

insert
iconv 進(jìn)行數(shù)據(jù)庫轉(zhuǎn)碼函數(shù)
fromusername

關(guān)鍵代碼如下：

$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "<xml>
      <ToUserName><![CDATA[%s]]></ToUserName>

    </xml>";  

     if(!empty( $keyword ))
     {
       //用 戶 名 : $user
       //密　　碼 : $pwd
       //主庫域名 : $host
       //從庫域名 : SAE_MYSQL_HOST_S
       //端　　口 : $port
       //數(shù)據(jù)庫名 : $dbname

       $dbname = "app_dq095";

       $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203";

       /*接著調(diào)用mysql_connect()連接服務(wù)器*/
       // 連主庫
       $db = mysql_connect($host,$user,$pwd);

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

       /*連接成功后立即調(diào)用mysql_select_db()選中需要連接的數(shù)據(jù)庫*/
       if (!mysql_select_db($dbname)) {
         die("Select Database Failed: " . mysql_error($db));
       }
   mysql_query("set names utf-8",$db); 

       /*至此連接已完全建立，就可對當(dāng)前數(shù)據(jù)庫進(jìn)行相應(yīng)的操作了*/
       /*！??！注意，無法再通過本次連接調(diào)用mysql_select_db來切換到其它數(shù)據(jù)庫了?。?！*/
       /* 需要再連接其它數(shù)據(jù)庫，請再使用mysql_connect+mysql_select_db啟動另一個連接*/

       /**
       * 接下來就可以使用其它標(biāo)準(zhǔn)php mysql函數(shù)操作進(jìn)行數(shù)據(jù)庫操作
       */

       $sql="SELECT * FROM `welcome`WHERE `user`= '" . iconv("UTF-8","GBK",$fromUsername) . "'";
       $query=mysql_query($sql);

       mysql_close($db);
     }else{
