Phalcon: PHP Framework

Phalcon Framework

Let's look at how MVC structure works in phalcon. The MVC platform creates web applications with three layers: model, view, and controller.

A view is a graphical representation of a model that interacts with the model and obtains data. It contains data that the end user sees as a result of submitting requests and receiving answers. A view is provided to the model when a user's request is accepted.

The controller serves as a bridge between the model and the display.

Models provide knowledge and a logical framework for integrating databases and carrying out CRUD (Create, Read, Update, and Delete) activities.

The model transforms and transmits to the controller a response presented to end users in the view layer.

Working

Let's understand the working of the phalcon framework in a stepwise manner.

• The end-HTTP user's request is routed to the controller.

 

• The end-user interacts with the view layer, or user interface, via a method or an event.

 

• The controller is in charge of methods and events.

 

• After that, the controller contacts the model layer by updating end-user activities.

 

• To create output, the view layer uses the model layer.

 

• The view layer retrieves data from its model since the model layer has no direct contact with it.

 

• The response is then displayed to the end user via the user interface.

 

• The user interface waits for further action from the end user, which initiates a new request and response cycle. 

Phalcon Directory Structure

Because Phalcon is loosely connected, the user can design any directory structure.

The root folder is the application's root folder. Any folder outside the root directory is unavailable to the web server and is not covered by the Phalcon project. 

When you create a project, the following directories will appear in your file system:

• App: Contains the heart of the application. The folder contains all of the script folders and files.

 

• Config: This subdirectory will contain all project configurations, basic settings, or third-party libraries. You can add a new third-party library or connect to a database by putting the required code in files in this folder.

 

• Controllers: Handles requests and responses. The subdirectory will include any controllers defined by the user.

 

• Models: Comprises all database interactions for retrieving and displaying data.

 

• Library: All external third-party libraries will be included in this folder.

 

• Migrations: The user can add or change files in this folder if data migration is required.

 

• A cache is critical to its function, and cache-related information is stored in this subdirectory.  

 

• Views: Views are used to present data to the user. This folder will contain information relating to the view layer, such as page content.

 

• Public: This folder contains CSS, JavaScript, metadata (data about data), pictures used in the program, files to be uploaded based on functionality, and temporary software data.

Advantages of the Phalcon Framework

• It is based entirely on the traditional MVC framework.

 

• Because it is written in C, it is simple to implement.

 

• It offers Laravel 4 Framework features, which is the best thing about it.

 

• Maintenance is the primary benefit due to well-structured readable files.

 

• Because Phalcon already has the entire framework in RAM, the entire set of framework files does not need to be processed. There are benchmarks on the website that demonstrate that this offers some significant performance improvements.

Disadvantages of the Phalcon Framework

• Installation is intricate in comparison to other frameworks.

 

• Does not support shared hosting. 

 

• If something goes wrong, debugging the C code will become problematic.

 

• Every request causes all files on the hard disk to be read, translated into bytecode, and then executed. Compared to other languages like Ruby (Rails) or Python, this results in significant performance loss like Django and Flask.
