我写了这段代码来加载一些视图。我想提取从数据库查询传递到视图的数组数据，然后显示它。我已经尝试过使用ob_start()和extract()函数，但似乎不起作用。我认为问题出在我的应用程序的控制器代码上，但我不知道如何解决它，任何帮助或建议将不胜感激。
模型类：
<?php
define( 'STORAGE_PATH', __DIR__ );
class CredentialsManager{
private $data;
private $input;
private $open;
private $decode;
private $encode;
public function __construct(){
$this->db = new PDO('sqlite:'.STORAGE_PATH.'/clients.db');
}
public function save(array $data){
if( isset( $data ) && is_array( $data ) ){
$data = [
$_POST['client_name'],
$_POST['hosting_provider'],
$_POST['client_domain'],
$_POST['username'],
$_POST['password'],
$_POST['ftp_host'],
$_POST['mysql_username'],
$_POST['mysql_password'],
$_POST['mysql_host'],
$_POST['wordpress_user'],
$_POST['wordpress_password']
];
$stmt = $this->db->prepare( "INSERT INTO clients_details (client_name,hosting_provider,client_domain,username,password,ftp_host,mysql_username,mysql_password,mysql_host,wordpress_user,wordpress_password) VALUES(?,?,?,?,?,?,?,?,?,?,?)" );
return $stmt->execute( $data );
}
}
public function search(string $data){
if( isset( $data ) && is_string( $data ) ){
$stmt = $this->db->prepare("SELECT * FROM clients_details WHERE client_name = ?");
$stmt->execute( array($data) );
$result = $stmt->fetchAll( PDO::FETCH_ASSOC );
if( $result > 0 ){
return json_encode($result);
}
}
}
}
?>
View.php类：
<?php
class View{
private $data;
public function __construct(){
}
public function search(){
require_once 'search.php';
}
public function searchResults(array $results_set){
ob_start();
extract( $results_set );
require_once 'search-results.php';
return ob_get_clean();
}
}
?>

</div>
</div>
</div>
</div>
这是其余代码，这些代码管理到控制器的路由并从db输出数据：
<?php
/**
* Controller Class
*/
class Controller{
private $view;
private $data;
public function __construct(){
$this->view = new View;
$this->model = new CredentialsManager;
}
public function index(){
return $this->view->index();
}
public function search(){
return $this->view->search();
}
public function processData(string $request_method, $data){
if( $request_method === 'POST' ){
return $this->model->save($_POST);
}
elseif( $request_method === 'GET' ){
$search_results = $this->model->search($data);
$results_set = json_decode($search_results, true);
return $this->view->searchResults($results_set);
}
}
}
$controller = new Controller;
if( isset($_SERVER['REQUEST_URI']) ){
$requested_uri = parse_url( $_SERVER['PATH_INFO'], PHP_URL_PATH);
if( $requested_uri === '' ){
echo $controller->index();
}
elseif( $requested_uri != '' ){
$method = ltrim( $requested_uri, '/');
echo @$controller->$method();
}
}
if( isset($_SERVER['REQUEST_METHOD']) ){
switch( $_SERVER['REQUEST_METHOD'] ){
case 'POST':
echo $controller->processData('POST', $_POST);
break;
case 'GET':
$q = parse_url( $_SERVER['REQUEST_URI'], PHP_URL_QUERY );
$search_term = ltrim( $q, 'q=');
echo $controller->processData('GET', $search_term);
break;
}
}
?>
PS: I need also to improve the route system, for now is a very dirt solution,it works well, but it will try to manage also the request for the templates page resources and this is not what I want.
