For instance the Regex patterns used to rewrite the incoming URL’s and how they resolve to local PHP files with optional GET query parameters added to the URL. I followed the ‘PHP:…

Note: the report below is written in Dutch. Vanuit de basisgedachte dat het project een begin is van een veel uitgebreider dashboard dat daadwerkelijk gebruikt gaat worden, ben ik eerst gaan onderzoeken wat de juiste opbouw van componenten voor de programmering en weergave zou kunnen zijn. Qua vormgeving en stijl heb ik gekeken naar de website van Winc Academy. Zo heb ik de keuze gemaakt om gebruik te maken van de kleuren lichtblauw, okergeel en licht- en donkergrijs, tegen een witte achtergrond…
