+# Examen PHP 1 - 08/03/2022
+
+De applicatie is een zeer eenvoudig order-systeem. Er zijn 3 klanten, waarvoor je en bestelling kan aanmaken. In de database kan je terugvinden welke productID's er zijn. Een bestelling aanmaken gebeurt in 2 stappen : eerst maak je het order aan (met een referentie), daarna kan je aan een bestaand order producten toevoegen.
+
+Probeer de applicatie uit, bekijk aandachtig de code. Veel zaken moeten duidelijk zijn, waar nodig staat er extra uitleg.
+
+> TIP: debug de applicatie en voeg zelf commentaar toe waar nodig om later snel aan de slag te gaan.
+
+## Installatie
+
+1. Fork deze repository (rechts boven) en maak mij collaborator (in de settings uiterst rechts)
+2. Clone deze repository in een aparte folder. 
+3. Installeer de libraries in vendor:  `docker run --rm -t -i -v ${PWD}:/app debaetsr/composer2 install`
+4. start de lokale server: `docker run --rm -t -i -v ${PWD}:/src -p 8080:8000 debaetsr/php_xdebug`
+5. Start de XDEBUG-server - deze configuratie staat reeds OK
+
+> Zie de mattermost voor meer info omtrent deze commando's, in de pinned posts
+
+### Opdracht
+
+De index.php bevat enkele routes en database connecties. Pas de applicatie aan zodat het voldoet aan het Model - View - Controller systeem.
+
+Maak gebruik van services en Twig! Alle dependencies zijn reeds geïnstalleerd indien je het  `composer install` commando (hierboven) uitgevoerd hebt.
+
+> TIP :  De namespace is reeds geconfigureerd voor de `/src` folder. Zoek eerst deze uit!
+
+Vergeet niet om gebruik te maken van commits en branches indien nodig. Je mag altijd je notities inscannen/fotograferen en doorsturen.
+
+Er zijn geen instinkers, maar heb wel aandacht voor details.
+
+> TIP : security is belangrijk!
