mysql数据库权限，只允许localhost连接，不能通过Internet连接

字符集转换

查询结果集不能直接输出，print($result)，紧紧输出资源代码Resource id #2

输出了3个JSON字符串，3对大括弧

3，android客户端如何解码？

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost("htttp:localhost/mysql.php");

httpPost.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));

//params:List php接收

HttpResponse httpResponse = httpClient.execute(httpPost);

HttpEntity httpEntity = httpResponse.getEntity();

is = httpEntity.getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));

StringBuilder sb = new StringBuilder();

String line = null;

while ((line = reader.readLine()) != null) {

sb.append(line + "\n");

}

is.close();

json = sb.toString();

return new JSONObject(json);
