Model View Controller(MVC) in PHP Tutorial. The model view controller pattern is the most used pattern for today’s world web applications.
It has been used for the first time in Smalltalk and then adopted and popularized by Java. At present there are more than a dozen PHP web frameworks based on MVC pattern. Despite the fact that the MVC pattern is very popular in PHP, is hard to find a proper tutorial accompanied by a simple source code example. That is the purpose of this tutorial. The MVC pattern separates an application in 3 modules: Model, View and Controller: The model is responsible to manage the data; it stores and retrieves entities used by an application, usually from a database, and contains the logic implemented by the application.
The above figure contains the MVC Collaboration Diagram, where the links and dependencies between figures can be observed: Our short php example has a simple structure, putting each MVC module in one folder: Controller Our Controller class has only one function and the constructor. .htaccess Tutorial. Introduction In this tutorial you will find out about the .htaccess file and the power it has to improve your website.
Although .htaccess is only a file, it can change settings on the servers and allow you to do many different things, the most popular being able to have your own custom 404 error pages. .htaccess isn't difficult to use and is really just made up of a few simple instructions in a text file. Will My Host Support It? This is probably the hardest question to give a simple answer to. Many hosts support .htaccess but don't actually publicise it and many other hosts have the capability but do not allow their users to have a .htaccess file. A good sign of whether your host allows .htaccess files is if they support password protection of folders. What Can I Do? You may be wondering what .htaccess can do, or you may have read about some of its uses but don't realise how many things you can actually do with it. Creating A .htaccess File Warning Custom Error Pages Part 2. Write your own PHP MVC Framework (Part 1) What is MVC?
From Wikipedia– Model–View–Controller (MVC) is an architectural pattern used in software engineering. 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. Why should I write my own framework? This tutorial is by no means a comprehensive/definitive solution to your framework needs.
So why should you write your own framework? More importantly, you have complete control over your framework. Lets dive right in. PHP Tutorials Examples Model View Controller MVC. Model View Controller MVC by Kevin Waterson Contents Abstract Model View Controller.
This tutorial will take you from the beginning to the end of building a MVC framework. What is MVC? MVC is a design pattern. In the MVC framework that is created in this tutorial, several key points will be raised. It is beyond the scope of this tutorial to show how to set up htaccess and mod_rewrite and more information on these can be gained from the Apache manual.
RewriteEngine on RewriteCond %{REQUEST_FILENAME} ! RewriteRule ^(.*)$ index.php? The .htaccess file will permit access to the site via urls such as If you do not have mod_rewrite available, the entry to the site will be the same, except that the URL will contain the values needed such as:
