Installing Phalcon on Hosting?

11 minutes read

Installing Phalcon on hosting involves several steps. Here's a general outline of the process:

  1. Check server requirements: Ensure that your hosting service meets the minimum requirements for running Phalcon. These typically include PHP version 7.2 or later, as well as certain PHP extensions like PDO, JSON, and Zlib.
  2. Verify availability: Confirm that Phalcon is supported on your hosting platform. Not all hosting providers may allow the installation of custom PHP extensions like Phalcon.
  3. Download Phalcon: Visit the official Phalcon website ( and download the appropriate version of Phalcon for your PHP setup.
  4. Compile Phalcon: Extract the downloaded Phalcon archive on your local machine. Inside, you'll find the Phalcon C-extension source code. Compile it to generate a binary extension file (e.g., or phalcon.dll) compatible with your hosting's PHP version.
  5. Copy the extension file: Upload the generated Phalcon extension file to your hosting server. Place it in the appropriate directory where PHP extensions are stored. This location may vary depending on your hosting environment, but it's commonly named "ext" or "extensions".
  6. Configure PHP: Open the php.ini configuration file on your hosting server. Locate the section where PHP extensions are enabled and add a line to enable the Phalcon extension. The line typically looks like: "" on Linux servers or "extension=phalcon.dll" on Windows servers.
  7. Restart the web server: After making changes to the PHP configuration, restart your web server to apply the modifications.
  8. Verify installation: Create a simple PHP script that calls the "phpinfo()" function and run it on your hosting server. The script will display information about the PHP environment. Look for a section indicating the presence of Phalcon; if it's there, the installation was successful.

It's important to note that the specific steps may vary depending on your hosting provider and server configuration. It's recommended to consult your hosting provider's documentation or support team for more precise instructions tailored to your hosting environment.

How to configure Phalcon after the installation on hosting?

To configure Phalcon after installation on hosting, follow these steps:

  1. Enable Phalcon extension: Make sure the Phalcon PHP extension is installed and enabled on your hosting. You can check whether it is enabled by creating a PHP file with the phpinfo() function, and then accessing that file through your browser. Search for "Phalcon" in the output to see if it's listed. If not, you may need to enable it in the PHP configuration file (php.ini).
  2. Create a Phalcon project: Set up a new folder for your Phalcon project on your hosting. This folder will hold all your project files and serve as the root directory.
  3. Setup a virtual host: Configure a virtual host on your hosting server to point to the root directory of your Phalcon project. This tells the server to serve the Phalcon project when the specified domain or URL is accessed.
  4. Set up database connection: Phalcon requires a database connection to work with database-related functionality. In your project, locate the config folder and find the config.php file. Edit this file to provide the necessary database connection details such as host, username, password, and database name.
  5. Set up the routing: Phalcon follows a routing pattern to handle different URLs and map them to corresponding controllers and actions. Open the routes.php file located in the config folder and define your desired routes.
  6. Configure the view engine: Phalcon supports various templating engines. You can configure the view engine of your choice in the services.php file located in the config folder.
  7. Test the configuration: Lastly, you can test the configuration by creating a simple controller and action, and then accessing it through your browser. If everything is properly configured, you should be able to see the output of your controller/action.

Note: The exact steps may vary depending on your hosting environment and preferences. It's recommended to consult your hosting provider's documentation or support if you encounter any issues during the configuration process.

How does Phalcon compare to other PHP frameworks for hosting installations?

Phalcon is a high-performance PHP framework that stands out from other frameworks due to its architecture and design philosophy. Here are some key points to consider when comparing Phalcon with other PHP frameworks for hosting installations:

  1. Performance: Phalcon is known for its exceptional performance. It achieves this by being implemented as a C extension for PHP rather than a pure PHP framework. This allows Phalcon to run at high speeds and utilize server resources efficiently.
  2. Efficiency: Phalcon's architecture is designed to be memory-friendly, reducing the amount of memory consumed by PHP. It also employs advanced caching mechanisms that enhance its efficiency.
  3. Modularity: Phalcon follows a loosely coupled architecture, allowing you to use only the components you need. This modular design gives you greater control over your application's size and performance.
  4. Learning Curve: Phalcon may have a slightly steeper learning curve compared to some other PHP frameworks because of its unique architecture and the need to compile and install the C extension. However, its extensive documentation and active community support make the learning process smoother.
  5. Database Support: Phalcon provides a wide range of database adapters, including MySQL, PostgreSQL, SQLite, and MongoDB. It also has an ORM (Object Relational Mapping) component, similar to other frameworks, to simplify database operations.
  6. Flexibility: Phalcon provides flexibility when it comes to choosing the application's database structure, URL routing, and view engine. It also offers support for different development styles, such as MVC (Model-View-Controller), Micro, and HMVC (Hierarchical Model-View-Controller).
  7. Extensibility: Phalcon allows you to extend its functionality easily through the use of plugins, middleware, and custom components. This extensibility makes it suitable for building complex applications with evolving requirements.

Overall, Phalcon's unique design and performance focus set it apart from other PHP frameworks. If speed and efficiency are crucial for your hosting installations, Phalcon could be an excellent choice. However, it's essential to consider your specific project requirements and evaluate the strengths and weaknesses of different frameworks to make an informed decision.

What are the requirements for installing Phalcon on hosting?

To install Phalcon on a hosting environment, you typically need the following requirements:

  1. PHP version: Phalcon requires PHP 7.2 or later. Make sure your hosting environment supports this version.
  2. C Compiler: Phalcon is a C extension for PHP, so you need a C compiler available on your hosting server. Check if your hosting provider allows the installation of C compilers. Commonly used C compilers are gcc or clang.
  3. Phalcon library: You need to install the Phalcon library on your server. You can either download the source code and compile it, or use a package manager like Composer.
  4. PHP Extension: Once the Phalcon library is installed, you need to enable the Phalcon PHP extension. This involves adding an extension line in your PHP configuration file (php.ini) or using a separate Phalcon configuration file, such as phalcon.ini or
  5. Web Server Configuration: You may need to configure your web server (e.g., Apache or Nginx) to recognize Phalcon. This involves adding necessary directives, such as loading the Phalcon PHP extension, setting up the document root, and configuring rewrite rules (if needed).

Note: The specific steps to install Phalcon may vary depending on your hosting provider and server setup. It is recommended to consult your hosting provider's documentation or support for detailed instructions.
