  1. First, create a new project on the Google Cloud Platform console by accessing the project dashboard.
  2. Open Google Shell, which can be found in the top-right corner of the Google Cloud Console.
  3. Use the following command to install Composer, a popular package manager for PHP: curl -sS https://getcomposer.org/installer | php
  4. Use the next command to create a new FuelPHP project and download its dependencies via Composer: php composer.phar create-project fuel/fuel
  5. After the download is completed, navigate to the project's directory using the following command: cd fuel
  6. Open the index.php file within the fuel/public directory using the nano text editor: nano public/index.php
  7. In the index.php file, change the value of FUEL_ENV from production to development. Save the changes and exit the editor.
  8. Use the next command to launch the FuelPHP development server: php oil server
  9. You will now see a message indicating that the server is running. Access the FuelPHP application by clicking on the web preview button in the Google Cloud console, or by visiting the server's IP address in your web browser.


That's it! You have successfully installed FuelPHP on Google Cloud and launched a development server to start building your application.

What is composer and how to install it?

Composer is a dependency management tool for PHP that allows you to manage and install external libraries and packages required by your PHP project. It helps to keep track of the versions of the packages you use and handles the autoloading of classes as well.


To install Composer, you can follow these steps:

  1. Download and install Composer globally on your system by executing the following command in your terminal (macOS / Linux) or command prompt (Windows):
1
$ curl -sS https://getcomposer.org/installer | php


This will download the composer.phar executable file.

  1. Next, move the composer.phar file to a directory that is included in your system's PATH environment variable. You can use the following command to move it to the /usr/local/bin/ directory (may require administrative permissions):
1
$ mv composer.phar /usr/local/bin/composer


If you encounter a permission error, you can try running the above command with sudo.

  1. Once installed, you can check that Composer is available by running the following command:
1
$ composer --version


This will display the installed version of Composer.


Now you can use Composer by navigating into your PHP project's directory and executing commands like composer install or composer require <package-name> to manage your dependencies.


What are the system requirements for FuelPHP?

The system requirements for FuelPHP are as follows:

  • PHP 5.3.3 or later version
  • Apache 2.x or Nginx web server
  • MySQL 5.1 or later, or any other compatible database system
  • PDO extension for PHP
  • OpenSSL extension for PHP
  • Fileinfo extension for PHP
  • MBString extension for PHP
  • Reflection extension for PHP
  • Composer (dependency manager for PHP) for installation and updates
  • GD extension for PHP (optional for image manipulation)
  • Intl extension for PHP (optional for internationalization)


These are the minimum requirements needed to run FuelPHP. However, it is recommended to use the latest stable versions of PHP and other dependencies for optimal performance and security.


What is a migration in FuelPHP?

In FuelPHP, a migration refers to a process of managing database schema changes over time. It is a way to keep track of database modifications by creating and applying a series of migration files. These files contain PHP code that can be executed to modify the database structure.


Migrations in FuelPHP provide a structured and organized approach to apply changes such as creating tables, adding or removing columns, altering indexes, and more. They can be easily managed, shared, and version-controlled, making it easier to collaborate with other developers.


By using migrations, developers can ensure that the database schema remains consistent across different environments and can easily roll back or forward the schema changes if needed. It is especially useful when working with teams, as everyone can synchronize their databases by running the migration files.


Overall, migrations in FuelPHP help to streamline the process of managing and updating database schemas in a controlled and structured manner.


How to configure environment-specific settings in FuelPHP?

To configure environment-specific settings in FuelPHP, you can use the config.php files located in the /fuel/app/config/ directory. These files allow you to define settings specific to different environments, such as development, testing, and production.


Here's how you can configure environment-specific settings in FuelPHP:

  1. Open the /fuel/app/config/config.php file and locate the 'default' array. This array defines the default settings for your application.
  2. Create separate config files for each environment by duplicating the config.php file. Rename the duplicated files to config.development.php, config.testing.php, and config.production.php.
  3. Open the index.php file located in the root directory of your FuelPHP installation.
  4. Find the following line of code:
1
define('ENVIRONMENT', isset($_SERVER['FUEL_ENV']) ? $_SERVER['FUEL_ENV'] : 'development');


This line sets the environment based on the FUEL_ENV server variable. If it's not specified, it defaults to 'development'.

  1. Specify the environment by setting the FUEL_ENV server variable in your web server configuration or .htaccess file. For example, if you're in the development environment, add the following line to your .htaccess file:
1
SetEnv FUEL_ENV development


  1. Open the bootstrap.php file located in the /fuel/app/ directory.
  2. Find the following line:
1
Fuel::$env = (isset($_SERVER['FUEL_ENV']) && file_exists(APPPATH . 'config/' . $_SERVER['FUEL_ENV'] . '/')) ? $_SERVER['FUEL_ENV'] : Fuel::DEVELOPMENT;


This line sets the FuelPHP environment based on the FUEL_ENV server variable. If the corresponding config file exists for the specified environment, it uses that environment. Otherwise, it defaults to Fuel::DEVELOPMENT.

  1. Set the appropriate environment for FuelPHP by modifying the line. For example, change it to:
1
Fuel::$env = Fuel::DEVELOPMENT;


This explicitly sets the environment to 'development'.

  1. Open the config.php file for the desired environment (e.g., config.development.php) and modify the settings as needed. You can override any settings from the default array to match your environment-specific requirements.
  2. Repeat the same process for other environment config files (config.testing.php and config.production.php).


By following these steps, FuelPHP will load the appropriate environment-specific config file based on the FUEL_ENV server variable. This way, you can configure different set of settings for each environment in your FuelPHP application.
