We're only needing this for our project this will not go online

Yo I got it

<?php
 include 'core/init.php';
include 'includes/overall/indexOver.php';

if (empty($_POST) === false){
	$username = $_POST['username'];
	$password = $_POST['password'];	
		
		 
	
	if(empty($username) === true || empty($password) === true) {
		//$errors = 'you need to enter username or password';
		echo "<script>alert(\"you need to enter username or password!\");</script>";
	} else if(user_exists($username) === false){
		//$errors= 'We can\'t find the username. Have you registered?';
		echo "<script>alert(\"We can\'t find the username. Have you registered?\");</script>";
	}	else if(user_active($username)=== false)	{
		$errors = 'please activate your account';
	}else{
	$login = login($username, $password);
			if($login === false){
				//$errors[] = 'your username or password is incorrect';
				echo "<script>alert(\"your username or password is incorrect?\");</script>";
			}else{
			
				$_SESSION['id'] = $login;
				header('Location: main1.php');
				exit();
			}
	}
	


	//print_r($errors);
	
	
}
?>
