A PHP framework called Phalcon Framework is web-based and based on the Model-View-Controller pattern. You should be familiar with HTMLCSS, and PHP before starting this blog and with the MVC framework. It would be beneficial and easier to understand if you have prior experience with other conventional frameworks like YiiLaravel, and Codeigniter.

What is Phalcon?

Andres Gutierrez and other developers created a relatively new PHP framework called  Phalcon, which was launched in 2012.

The Berkeley Source Distribution license has been applied to the open-source Phalcon Framework. Creators used PHP and C to create the Phalcon web server extension, a language hybrid. Compared to other frameworks, it speeds up execution and can handle more HTTP requests per second, offering incredible potential and lightning-fast performance.


The Phalcon framework was created so that developers could create apps with excellent performance and minimal power consumption.

Due to its distinctive design, the framework can always run in memory, providing all of its features whenever required without the costly file metrics and file reads used by other PHP frameworks. It includes capabilities like object-relational mapping, a templating engine, a request object librarypagination, and caching, and, as was already said, it encourages the MVC design.

Phalcon is distinct since it can be downloaded and installed as a PHP module. The installation procedure takes a few minutes, and the literature includes installation instructions. 

The C and Zephir computer languages are used to write most of them. Without any prior C programming experience, PHP applications may be created using the Phalcon framework.


  • Phalcon's development aimed to produce a web server extension; that improves execution rates, lowers resource use, and guarantees faster request processing than competing PHP frameworks.


  • Effective memory use is Phalcon's leading competitive edge. 


  • This eliminates the need to keep any data off-memory, unlike most other PHP frameworks, which rely on costly operations like file reads and file stats. 


  • Phalcon improves efficiency and maximizes performance by doing away with this requirement.


  • For developers to utilize Phalcon, knowing the C programming language is optional. Its interface is available for usage as exposed PHP classes in the Phalcon namespace.


  • Phalcon is loosely linked; developers can only utilize the items they require as glue components for their applications depending on the application's demands.


  • Phalcon is a community-driven project; therefore, you may submit a New Feature Request to express your ideas and ask for the features you want, making it completely open-source.


To understand its benefits, let's evaluate it against other well-known PHP frameworks like YiiLaravel, and Codeigniter.

  • Several components in phalcon require less code than others to complete tasks.


  • Knowing Model View Controller or Object Relational Modeling will be helpful for the developer utilizing Phalcon.


  • Each component of Phalcon combines PHP and C and may be used independently as a module.


  • Phalcon develops a standalone framework.


  • Web applications are created using developer tools with CRUD (Create, Read, Update, and Delete ) capabilities.


  • Phalcon is adaptable because Zephir, a high-level programming language, is present.

Phalcon Framework

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


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.


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.


  • 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.
