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 = "<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 ))

{

//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...";

}

index.php代码如下

<?php
