What is MVC in CakePHP?
September 2, 2024

Answer: Answer: MVC stands for Model-View-Controller. It’s a design pattern that separates the application into three interconnected components:

  • Model: Manages the data and business logic.
  • View: Represents the presentation layer (UI).
  • Controller: Handles user input and interaction, modifying the data in the model or changing the view’s output.

How do you install CakePHP?
September 2, 2024

To install CakePHP, follow these steps to set up the framework on your local machine or server:

Step 1: Check System Requirements

Ensure your system meets the minimum requirements for CakePHP:

  • PHP version: 7.4 or higher.
  • Web server: Apache, Nginx, etc.
  • Database: MySQL, PostgreSQL, SQLite, or other supported databases.
  • Composer: Dependency management tool for PHP (required).

Step 2: Install Composer

If Composer is not already installed, you can install it by running the following command in your terminal:

Example

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"

Then, move the composer.phar file to a global location:

Example

sudo mv composer.phar /usr/local/bin/composer

Step 3: Create a New CakePHP Project

Once Composer is installed, you can create a new CakePHP project using the following command:

Example

composer create-project --prefer-dist cakephp/app my_cakephp_app
  • Replace my_cakephp_app with the desired name for your project.
  • Composer will download CakePHP and set up the directory structure.

Step 4: Set Up Database Configuration

After the project is created, configure the database connection by editing the config/app_local.php file:

Example

<?php
// In config/app_local.php
'Datasources' => [
    'default' => [
        'host' => 'localhost',
        'username' => 'your_db_username',
        'password' => 'your_db_password',
        'database' => 'your_db_name',
        'driver' => 'Cake\Database\Driver\Mysql', // Or other database driver
        // Other database settings...
    ],
],
?>

Replace the placeholder values with your actual database credentials and settings.

Step 5: Set File Permissions

Ensure that the tmp and logs directories are writable by the web server:

Example

sudo chmod -R 775 tmp/
sudo chmod -R 775 logs/

Step 7: Start CakePHP

You can now run the built-in CakePHP server for local development:

Example

bin/cake server

This will start the CakePHP server on http://localhost:8765.

Step 8: Access Your CakePHP Application

Open your browser and navigate to the project URL (e.g., http://localhost:8765 or http://my_cakephp_app.local if using a virtual host). You should see the CakePHP welcome page.

What are CakePHP’s conventions?
September 2, 2024

Answer: Answer: CakePHP follows a set of conventions for things like file naming, class names, database table names, and function names to ensure consistency and reduce configuration. Some conventions include:

  • Table names should be plural (e.g., articles for an Article model).
  • Model class names should be singular and capitalized (e.g., Article for articles table).
  • Controller names should be plural (e.g., ArticlesController).
