Restful Web Service无法从实时服务器PHP获取任何数据

Question

I have created restful webservices in php to connect data with app. In my localhost I am getting everything but I am not getting any output in godaddy server.

<?php   
require_once("Rest.inc.php");

class API extends REST {    
    public $data = "";      
    const DB_SERVER = "localhost";
    const DB_USER = "root";
    const DB_PASSWORD = "";
    const DB = "beta01";        
    private $db = NULL; 
    public function __construct(){
        parent::__construct();              
        $this->dbConnect();                 
    }       
    private function dbConnect(){
        $this->db = mysql_connect(self::DB_SERVER,self::DB_USER,self::DB_PASSWORD);
        if($this->db)
            mysql_select_db(self::DB,$this->db);
    }       
    public function processApi(){
        $func = strtolower(trim(str_replace("/","",$_REQUEST['rquest'])));
        if((int)method_exists($this,$func) > 0)
            $this->$func();
        else
            $this->response('',404);                
    }

private function users(){   

        if($this->get_request_method() != "GET"){
            $this->response('',406);
        }
        $sql = mysql_query("SELECT * FROM users", $this->db);
        if(mysql_num_rows($sql) > 0){
            $result = array();
            while($rlt = mysql_fetch_array($sql,MYSQL_ASSOC)){
                $result[] = $rlt;
            }

            $this->response($this->json($result), 200);
        }
        $this->response('',204);    
    }
