Php empty result - php

Question

The result I get in the query I run with Mysql is the result I want. But when I send the same values ​​in my php code (even though the query is the same), it returns null.The query is a bit long but I thought I could do it. Trying a few things to improve myself
SELECT user_pictures.picture,users.username,
star,quest1.answer1,quest2.answer2,
quest3.answer3,quest4.answer4,quest5.answer5,
votes.created_at
FROM votes
LEFT JOIN user_pictures ON votes.voted_image_id=user_pictures.ID
LEFT JOIN users ON votes.voting_id=users.ID
LEFT JOIN quest1 ON votes.q1=quest1.ID
LEFT JOIN quest2 ON votes.q2=quest2.ID
LEFT JOIN quest3 ON votes.q3=quest3.ID
LEFT JOIN quest4 ON votes.q4=quest4.ID
LEFT JOIN quest5 ON votes.q5=quest5.ID
WHERE voted_id = "123456"
AND voting_id = "123"
how can i get the same result in my php code
<?php
require_once('connection.php');
if($_GET){
$voted_id = $_GET['voted_id'];
$voting_id = $_GET['voting_id'];
$sql = "SELECT user_pictures.picture,users.username,
star,quest1.answer1,quest2.answer2,
quest3.answer3,quest4.answer4,quest5.answer5,
votes.created_at
FROM votes
LEFT JOIN user_pictures ON votes.voted_image_id=user_pictures.ID
LEFT JOIN users ON votes.voting_id=users.ID
LEFT JOIN quest1 ON votes.q1=quest1.ID
LEFT JOIN quest2 ON votes.q2=quest2.ID
LEFT JOIN quest3 ON votes.q3=quest3.ID
LEFT JOIN quest4 ON votes.q4=quest4.ID
LEFT JOIN quest5 ON votes.q5=quest5.ID
WHERE voted_id = ?
AND voting_id = ? ";
$stmt = $connect->prepare($sql);
$stmt->bind_param("ii", $voted_id, $voting_id);
$stmt->execute();
$result = $stmt->get_result();
$data = $result->fetch_all(MYSQLI_ASSOC);
header('Content-Type:application/json;charset=urf-8');
echo json_encode($data);
}
?>
When I use var_dump($data) and var_dump($_GET) I can get the result I got in sql
array(2) {
[
"voting_id"
]=>
string(6) "123456"
[
"voted_id"
]=>
string(3) "123"
}
array(2) {
