<?php

    'number' => "+380XXXXXXXXX",
    'sender' => "Test name",
    'login' => "Login",
    'password' => "Pass",
    'tema' => "test",

$name = $db->safesql($member_id['name']);

            $pdo->query("SET NAMES utf8;"); 
            $pdo->query("INSERT INTO `{$sms_config['login']}` (`number`,`message`,`sign`) VALUES ('$r','$m','{$sms_config['sender']}')"); 
        }
