php微信公众号开发之欢迎老朋友
本文实例为大家分享了php微信公众号开发之欢迎老朋友的具体代码，供大家参考，具体内容如下
介绍数据库
insert
iconv 进行数据库转码函数
fromusername
关键代码如下：
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "
%s
0
";
if(!empty( $keyword ))
{
//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*/
/*！！！注意，无法再通过本次连接调用mysql_select_db来切换到其它数据库了！！！*/
/* 需要再连接其它数据库，请再使用mysql_connect+mysql_select_db启动另一个连接*/
/**
* 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
*/
$sql="SELECT * FROM `welcome`WHERE `user`= '" . iconv("UTF-8","GBK",$fromUsername) . "'";
$query=mysql_query($sql);
$rs=mysql_fetch_array($query);
$b= $rs['user'];
$c=iconv("GBK","UTF-8",$b);
$msgType = "text";
if ($c==$fromUsername)
{
$contentStr = "欢迎老朋友!";
}else{
$sql="INSERT INTO `welcome`(`id`,`user`) VALUES (NULL,'{$fromUsername}')";
mysql_query($sql);
$contentStr = "欢迎新朋友!";
}
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;
mysql_close($db);
}else{
echo "Input something...";
}
