注册android系统错误php

Question

我想做一个android登录系统，当我尝试注册时，我得到的是用户未能存储，我无法找到错误。我正在使用000webhost，我不知道它是否与此有关。请帮助和谢谢

我有Internet权限，并且登录正在工作，所以我认为不是连接或数据库的问题。当我尝试注册时，代码将转到“用户未能存储”部分，打印出“注册时发生未知错误！”。

这是register.php：

<?php 
    require_once 'include/DB_Functions.php'; 

$db = new DB_Functions(); 
// json response array 
$response = array("error" => FALSE); 

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password'])) { 

    // receiving the post params 
    $name = $_POST['name']; 
    $email = $_POST['email']; 
    $password = $_POST['password']; 

    // check if user is already existed with the same email 
    if ($db->isUserExisted($email)) { 
     // user already existed 
     $response["error"] = TRUE; 
     $response["error_msg"] = "User already existed with " . $email; 
     echo json_encode($response); 
    } else { 
     // create a new user 
     $user = $db->storeUser($name, $email, $password); 
     if ($user) { 
      // user stored successfully 
      $response["error"] = FALSE; 
      $response["uid"] = $user["unique_id"]; 
      $response["user"]["name"] = $user["name"]; 
      $response["user"]["email"] = $user["email"]; 
      $response["user"]["created_at"] = $user["created_at"]; 
      $response["user"]["updated_at"] = $user["updated_at"]; 
      echo json_encode($response); 
     } else { 
      // user failed to store 
      $response["error"] = TRUE; 
      $response["error_msg"] = "Unknown error occurred in registration!"; 
      echo json_encode($response); 
     } 
    } 
} else { 
    $response["error"] = TRUE; 

    $response["error_msg"] = "Required parameters (name, email or password) is missing!"; 
    echo json_encode($response); 
} 
?> 

这是DB_Functions.php类：

<?php 

class DB_Functions { 

    private $conn; 

    // constructor 
    function __construct() { 
     require_once 'DB_Connect.php'; 
     // connecting to database 
     $db = new Db_Connect(); 
     $this->conn = $db->connect(); 
    } 

    // destructor 
    function __destruct() { 

    } 

    public function consigueResultado($stmt) { 
     $RESULT = array(); 
     for ($i = 0; $i < $stmt->num_rows; $i++) { 
      $Metadata = $stmt->result_metadata(); 
      $PARAMS = array(); 
      while ($Field = $Metadata->fetch_field()) { 
       $PARAMS[] = &$RESULT[ $i ][ $Field->name ]; 
      } 
      call_user_func_array(array($stmt, 'bind_result'), $PARAMS); 
      $stmt->fetch(); 
     } 
     return $RESULT; 
    }

好吧，我得到它的，而不是使用PDO使用过时的版本工作MySQL的。代码和数据库是正确的（我认为），我相信它给了我错误，因为000webhost不支持PDO或mysqli库。
