Internal class method call - undefined?

[TekiusFanatikus]

Fatal error: Call to undefined function getDB() in C:\...\xampp\htdocs\DAL.php  on line 10

 

test.php

include 'DAL.php';

$DALClass = new DAL();

if($results = $DALClass->getData()){
...
}

 

DAL.php

<?php
class DAL {

function getDB(){	
	return $mysqli = new mysqli('localhost','root','','mytest');	
}

public function getData(){

	$db = getDB();
	return $result = $db->query("select * from tbl_main");	
} 
}
?>

 

I'm coming from another coding platform and trying to replicate my knowledge in PHP.

$this->getDB();

Thanks, this works!

 

I found another solution that had a class extending mysqli for a DAL... I suppose that approach would be better or would my approach be equally as good?
