表单成功后重定向到特定页面

Question

我是一个初学者，从成功开始我不知道如何重定向到特定页面：

if ( !empty($errors)) {
    $data['success'] = false;
    $data['errors']  = $errors;
}
else{

    $curl = curl_init();

    curl_setopt_array($curl, array(
        CURLOPT_URL => "https://api.sendinblue.com/v3/contacts",
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => '{"email":"'.$email.'", "updateEnabled":true, "listIds":[8], "attributes" : {"NOM":"'.$nom.'", "NIVEAU":"'.$niveau.'", "OPT-IN_METHOD":"FORMULAIRE"}}',
        CURLOPT_HTTPHEADER => array(
            "accept: application/json",
            "api-key: KEY ",
            "content-type: application/json"
        ),
    ));

    $response = curl_exec($curl);
    $err = curl_error($curl);

    curl_close($curl);

    if ($err) {
        echo "cURL Error #:" . $err;
    }
    $data['success'] = true;
    $data['message'] = 'Success!';
}

echo json_encode($data);

}

我尝试了许多解决方案，但我完全迷失了。

感谢您的帮助
