我这里有个类似的例子：
数据库配置信息：
<?php
//数据库配置信息(用户名,密码，数据库名，表前缀等)
$cfg_dbhost = "localhost";
$cfg_dbuser = "root";
$cfg_dbpwd = "1";
$cfg_dbname = "test";
$cfg_dbprefix = "";
$link = mysql_connect($cfg_dbhost,$cfg_dbuser,$cfg_dbpwd);
mysql_select_db($cfg_dbname);
mysql_query("set names utf8");
?>
接收答世早数据：
<?php
header("Content-type:text/html;charset=utf-8");
include "config.php";
//post接收数据,只是演示效果,这里就省去验证了
$name = $_POST['name'];
$content = $_POST['content'];
$sql = "insert into test (name,content) values ('{$name}','{$content}');";
$res = mysql_query($sql,$link);
if($res){
echo '{"name": "'.$name.'","content": "'.$content.'","status": "1"}';
}
?>
