Basic project Structure sayed@justetc.net

Loading Initial Components and Resources • The Bootstrap class loads the initial resources and components • application/controllers/ as the default directory in which to look for action controllers sayed@justetc.net

Initial Configuration of your application • File used • application/configs/application.ini sayed@justetc.net

Action Controllers [IndexController] • Associated Directory • /controller/action sayed@justetc.net

Error Controller sayed@justetc.net

Views • Views are written in plain old PHP • View scripts are placed in • application/views/scripts/ • And further categorized • using the controller names • Hence, we can create • Sub-directories • index/ • error/ • Within these subdirectories • you will find and create view scripts • that correspond to each controller action exposed • Our default case • index/index.phtml • error/error.phtml. sayed@justetc.net

Create Virtual Host sayed@justetc.net

Update Hosts File • C:\WINDOWS\system32\drivers\etc • 127.0.0.1 quickstart.local sayed@justetc.net
