pdo probleem
ik ben bezig om een pdo class te schrijven en loop tegen het volgende probleem :
Fatal error: Non-static method PDO::query() cannot be called statically in D:\Program Files\devel\xampp\htdocs\Mailchimp\demo\classes\db.class.php on line 189
de line waar het om gaat is de volgende
Code (php)
het probleem doet zich voor op het moment dat ik een select query wil uit voeren via de getArray() functie

iemand suggesties
Een niet static function roep je op met
Code (php)

<?php
$pdo= new PDO();
$pdo->query();
?>
$pdo= new PDO();

En niet zoals jij dat doet
