Array ( ) - Only showing! - login.php

I'v been stuck on this now for the past 4 hours!

I'm trying to get this code to prompt a user with the right error when not entering the right pass or username but its just prompting with Array ( )

<?php
include 'core/init.php';

if (empty($_POST) === false) {
	$username = $_POST['username'];
	$password = $_POST['password'];

	if (empty($username) === true || empty($password) === true) {
		$erros[] = 'You need to enter a username and password!';
	} else if (user_exists($username) === false) {
		$erros[] = 'We can\'t find that username. Have you registerd?';	
	} else if (user_active($username) === false) {
		$erros[] = 'You havn\'t activated your account!';
	} else {
		$login = login($username, $password);
		if ($login === false) {
			$errors[] = 'That username/password combination is incorrect!';
		} else {
			$_SESSION['iduser'] = $login;
			header('Location: index.php');
			exit();
		}	
	}
	
	print_r($errors);
}	
?>

Thanks,
