錯誤獲取我的數組MVC

Question

當我嘗試print_r（$結果）它獲取數組。數組（[0] =>數組（[id] => 6 [0] => 6 [ref] => GSO 646 & 647 [1] => GSO 646 & 647）[1] => ] => 7 [0] => 7 [ref] => GSO 962 [1] => GSO 962）[2] =>陣列（[id] => 8 [0] => 8 [ref] => GSO ASTM F 1923 [1] => GSO ASTM F 1923）

但我有一個錯誤，也許錯誤是在foreach，因爲它說無效的供應foreach（）。任何人都可以幫我嗎？謝謝你

模型

require_once("DatabaseManager.php"); 

class Model 
{ 

    public $connection; 

    public function __construct(){ 
     $connection = new DatabaseManager(); 
     $this->connection = $connection->getConnection(); 
    } 

    public function getAllRecords() 
    { 
     $sql = "SELECT * FROM reference"; 
     $query = $this->connection->query($sql); 
     $result = $query->fetchAll(); 
     //print_r($result); 
    } 
} 

控制器

require_once("../model/Model.php"); 

class Controller 
{ 
    private $model; 

    public function __construct() 
    { 
     $this->model = new Model(); 
    } 

    public function displayAllRecords() 
    { 
     $result = $this->model->getAllRecords(); 
     return $result; 
    } 
} 

VIEW

require '../controller/Controller.php'; 

$controller = new Controller(); 

foreach($controller->displayAllRecords() as $records) { 
. 
. 
} 

Answer 1

嘗試返回$這個 - >模型 - > getAllRecords（）;從您的控制器displayAllRecords（）方法，這樣

public function displayAllRecords() 
{ 
    return $this->model->getAllRecords(); 
} 

和

public function getAllRecords() 
    { 
     $sql = "SELECT * FROM reference"; 
     $query = $this->connection->query($sql); 
     return $result = $query->fetchAll(); 
     //print_r($result); 
    }
