DataStructureByDSamantaPdfSoftwareWrite your own PHP MVC Framework Part 1What is MVC From WikipediaModelViewController MVC is an architectural pattern used in software engineering. Data-Structures-Using-C-International-Edition-1418582-8ba334beda594ac8d960.jpg' alt='Data Structure By D Samanta Pdf Software' title='Data Structure By D Samanta Pdf Software' />Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information the data of the application the view corresponds to elements of the user interface such as text, checkbox items, and so forth and the controller manages the communication of data and the business rules used to manipulate the data to and from the model. In simpler words 1. Model handles all our database logic. Using the model we connect to our database and provide an abstraction layer. Controller represents all our business logic i. View represents our presentation logic i. HTMLXMLJSON code. Why should I write my own frameworkThis tutorial is by no means a comprehensivedefinitive solution to your framework needs. There are a lotofgoodphpframeworks out there. So why should you write your own framework Firstly, it is a great learning experience. You will get to learn PHP inside out. You will get to learn object oriented programming, design patterns and considerations. More importantly, you have complete control over your framework. Your ideas can be built right into your framework. Data Structure By D Samanta Pdf Software' title='Data Structure By D Samanta Pdf Software' />Web oficial de la Universidade da Corua.

The Directory Structure. Although we will not be a couple of directories mentioned above for this tutorial, we should have them in place for future expansion. Let me explain the purpose of each directory application application specific code config databaseserver configurationdb database backupslibrary framework codepublic application specific jscssimagesscripts command line utilitiestmp temporary data Once we have our directory structure ready, let us understand a few coding conventions. Coding Conventions. SQL tables will always be lowercase and plural e. Models will always be singular and first letter capital e. Item, Car. 3. Controllers will always have Controller appended to them.

The next move is to remove global variables and magic quotes. Another function that we make use of is autoload which helps us load our classes automagically. Finally, we execute the call. Hook function which does the main processing. First let me explain how each of our URLs will look yoursite. Nameaction. Namequery. String. So call. Hook basically takes the URL which we have received from index. String. model is the singular version of controller. URL is todo. comitemsview1first item, then. Controller is items. Model is item corresponding mysql tableView is delete. Action is delete. Query String is an array 1,first itemAfter the separation is done, it creates a new object of the class controller. Controller and calls the method action of the class. Now let us create a few classes first namely our base Controller class which will be used as the base class for all our controllers, our Model class which will be used as base class for all our models. First the controller. Controller. protected model. Templatecontroller,action. The above class is used for all communication between the controller, the model and the view template class. It creates an object for the model class and an object for template class. The object for model class has the same name as the model itself, so that we can call it something like this Item select. All from our controller. While destroying the class we call the render function which displays the view template file. Now let us look at our model. Model extends SQLQuery. DBHOST,DBUSER,DBPASSWORD,DBNAME. The Model class extends the SQLQuery class which basically is an abstraction layer for the my. SQL connectivity. Depending on your requirements you can specify any other DB connection class that you may require. Now let us have a look at the SQLQuery. SQLQuery. protected db. Handle. protected result. Connects to database.
