What are the MVC Guidelines for PHP Developers?

Model View Controller (MVC) is a design pattern governing the fundamental law that application logic must be segregated from the presentation. A number of PHP developers, both amateur and experienced, look forward to integrate MVC into their development script during PHP web development process. However, information on the web is minimal and the existing ones make use of phrases and glossary that would not be easily understood by a beginner.

At the outset, MVC was viewed as design patterns that were to be utilized along with Smalltalk by Trygve Reenskaug in the year 1979. “Applications Programming in Smalltalk-80: How to use Model View Controller”- This paper by Reenskaug laid foundation for all future MVC architectures. Simply put, MVC offers an uncomplicated way to segregate application logic from display. The fundamental idea with MVC is to segregate apps into three parts namely

1.  Model
2.  View
3.  Controller

Controller, in PHP web development process, is directly associated with the View and Model and so does View over the model. Nevertheless, the Model Lays inferred association on the View and then over Controller.

Inferred associations can be classified as associations which are viable from the point of view of the user, but not the original software design.

PHP-ModifiesFollowing is the way in which the interaction takes place.

–  By submitting forms or clicking links users interact with “View”
–  By transferring information to Model controller manages user input
–  Model receives the information and adds to the database
–  The view checks the update and responds accordingly
–  The View also awaits the upcoming user interaction

It might seem that MVC is a great solution for amateurs. Yet, segregating logic from the display is an age old concept. With MVC one can consider it as a streamline process. With simple layouts and code presentations it is possible to regulate apps.

Business Logic

It involves calculating logical processes present in an application. For instance, in case of a calendar, the job of Business Logic would be to classify the day, date, month, etc.

Templates

A number of MVC frameworks make use of templates to administrate DRY, facilitating easy code reuse without any requirement of rewriting. However, new developers must be cautioned that some templates might have complex syntax and you will not want to learn a completely new language. The better option would be to grasp them prior to the beginning of the development process.

DRY

DRY is one of the most critical implementations of MVC architecture. The full form of the acronym DRY is ‘Don’t Repeat Yourself’. It is also utilized by Ruby on Rails (ROR) which helps developers, performing PHP web development, to use once created codes a number of times. The principles governing DRY suggest that modifying a single element doesn’t result in disturbance of non-related elements. The DRY principle can be easily understood by someone who is good at ROR.

Convention over Configuration

Convention over configuration is accomplished by establishing sufficient frameworks for each and every convention. With minor changes needed it becomes quite easier. Convention over configuration is a design paradigm which mainly focuses on eliminating the quantity of decision making.

MVC is well known for generating clear, powerful, scalable, and fast coding which involves minimal investment of time and effort. PHP web development experts would find it worth experimenting with some frameworks prior to going with the best.
