Hello!!

Im having trouble connecting my register/login to phpmyadmin. Here is my code:

Server.php
Code: 
<?php
session_start();

// initializing variables
$username = "";
$email    = "";
$errors = array(); 

// connect to the database
$db = mysqli_connect('db5000289773.hosting-data.io', 'dbu499275', 'Gal%1981', 'dbs283083');

// REGISTER USER
if (isset($_POST['reg_user'])) {
  // receive all input values from the form
  $username = mysqli_real_escape_string($db, $_POST['username']);
  $email = mysqli_real_escape_string($db, $_POST['email']);
  $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
  $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);

  // form validation: ensure that the form is correctly filled ...
  // by adding (array_push()) corresponding error unto $errors array
  if (empty($username)) { array_push($errors, "Username is required"); }
  if (empty($email)) { array_push($errors, "Email is required"); }
  if (empty($password_1)) { array_push($errors, "Password is required"); }
  if ($password_1 != $password_2) {
	array_push($errors, "The two passwords do not match");
  }

  // first check the database to make sure 
  // a user does not already exist with the same username and/or email
  $user_check_query = "SELECT * FROM users WHERE username='$username' OR email='$email' LIMIT 1";
  $result = mysqli_query($db, $user_check_query);
  $user = mysqli_fetch_assoc($result);
  
  if ($user) { // if user exists
    if ($user['username'] === $username) {
      array_push($errors, "Username already exists");
    }

    if ($user['email'] === $email) {
      array_push($errors, "email already exists");
    }
  }

  // Finally, register user if there are no errors in the form
  if (count($errors) == 0) {
  	$password = md5($password_1);//encrypt the password before saving in the database

  	$query = "INSERT INTO users (username, email, password) 
  			  VALUES('$username', '$email', '$password')";
  	mysqli_query($db, $query);
  	$_SESSION['username'] = $username;
  	$_SESSION['success'] = "You are now logged in";
  	header('location: index.php');
  }
}

// LOGIN USER
if (isset($_POST['login_user'])) {
  $username = mysqli_real_escape_string($db, $_POST['username']);
  $password = mysqli_real_escape_string($db, $_POST['password']);

  if (empty($username)) {
  	array_push($errors, "Username is required");
  }
  if (empty($password)) {
  	array_push($errors, "Password is required");
  }

  if (count($errors) == 0) {
  	$password = md5($password);
  	$query = "SELECT * FROM users WHERE username='$username' AND password='$password'";
  	$results = mysqli_query($db, $query);
  	if (mysqli_num_rows($results) == 1) {
  	  $_SESSION['username'] = $username;
  	  $_SESSION['success'] = "You are now logged in";
  	  header('location: index.php');
  	}else {
  		array_push($errors, "Wrong username/password combination");
  	}
  }
}

Do you have error reporting turned on?

Code: 
/* Turn on error reporting */
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);

if (filter_input(INPUT_SERVER, 'SERVER_NAME', FILTER_SANITIZE_URL) == "localhost") {
    error_reporting(-1); // -1 = on || 0 = off
} else {
    error_reporting(0); // -1 = on || 0 = off
    ini_set('session.cookie_lifetime', 0);
// Prevents javascript XSS attacks aimed to steal the session ID
    ini_set('session.cookie_httponly', 1);

// **PREVENTING SESSION FIXATION**
// Session ID cannot be passed through URLs
    ini_set('session.use_only_cookies', 1);

// Uses a secure connection (HTTPS) if possible
    ini_set('session.cookie_secure', 1);
