No result on PHP value Mysqli stmt - php

Question

there's no result on my sqli request .. like empty data.. i'm pretty sure in my database there's much data
here's my code, correct me if i got mistake on my code
<?php
// include db handler
class DB_Functions {
private $conn;
// constructor
function __construct() {
require_once 'include/DB_Connect.php';
// connecting to database
$db = new Db_Connect();
$this->conn = $db->connect();
}
// destructor
function __destruct() {
}
function getSliderList(){
$stmt = $this->conn->prepare("SELECT cPID, image FROM sliderImage");
$stmt->execute();
if ($stmt->num_rows > 0 ) {
$result = $stmt->get_result()->fetch_assoc();
$response[] = $result;
$stmt->close();
echo json_encode($response);
return true;
} else {
// user not found
return false;
}
}
}
$x = new DB_Functions();
$user = $x->getSliderList();
$response = Array();
if($user){
$user;
return false;
} else {
$response['error'] = "Sorry an error occured. Our Problem, not you.";
return true;
}
?>
my DB request to connect
<?php
class DB_Connect {
private $conn;
// Connecting to database
public function connect() {
require_once 'include/Config.php';
// Connecting to mysql database
$this->conn = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);
// return database handler
return $this->conn;
}
}
?>
and config.php file
<?php
/**
* Database config variables
*/
define("DB_HOST", "localhost");
define("DB_USER", "bxxx");
define("DB_PASSWORD", "xxxx");
define("DB_DATABASE", "xxxx");
?>
i want to put the result into array.. and send this data using json_encode to use it in my app...

I don't think you need a prepared statement here, since you're not parameterizing any data. Try a simple query instead
$stmt = $this->conn->query("SELECT cPID, image FROM sliderImage");
$response = array();
while($result = $stmt->fetch_assoc()) {
$response[] = $result;
}
echo json_encode($response);
return true;
