Slim Framework Starter Template

A lightweight MVC web application starter template built on top of the Slim PHP microframework. Ideal for projects that require Slim's simplicity without sacrificing the benefits of a clean MVC architecture.

Why Using this Template?

This template provides a starting point for building web applications with the Slim 4 framework using the classic MVC (Model–View–Controller) pattern. It includes everything you need to get started, without the extra complexity of larger frameworks.

What's Included

This starter template follows best practices and adheres to industry standards:

• Slim 4: The "slim" PHP microframework
• Routing: Slim's custom routing based on FastRoute
• Dependency injection container (PSR-11)
• HTTP message interfaces (PSR-7)
• HTTP Server Request Handlers, Middleware (PSR-15)
• Autoloader (PSR-4)
• Logger (PSR-3)
• Code styles (PSR-12)
• Composer - Dependency management

Requirements

• PHP 8.2 or higher
• Composer (for dependency management)
• A web server (Apache, Nginx)

How Do I Use/Deploy this Template?

• Option 1: Using Composer (Recommended)
• Option 2: Using Docker (macOS/Linux/Windows)
• Option 3: Manual Installation

Option 1: Using Composer (Recommended)

Prerequisites:

• PHP 8.2 or higher installed locally
• Composer installed globally
• A web server (Apache/Nginx) or Wampoon

Don't have a WAMP/LAMP stack installed? Use Option 2: Docker instead.

1. Open a terminal in your web server's document root (i.e., htdocs).

2. Run the following command:

   Replace [project-name] with your project name (e.g., worldcup-app).

3. Open your [project-name]-app folder in VS Code.
4. Adjust your database credentials in config/env.php (see below).

Option 2: Using Docker (macOS/Linux/Windows)

Docker allows you to run the application in containers without installing PHP, Apache, or MariaDB locally. This works on macOS, Linux, and Windows.

Prerequisites:

• Install Docker Desktop
• Install Git

Quick Start:

1. Clone the repository (since Composer requires PHP, which you may not have installed):

   Replace [project-name] with your project name (e.g., worldcup-app).

2. Navigate to the project folder:

3. Remove the .git folder to start fresh with your own repository:

4. Start all containers by executing the following command:

   Note: Use docker-compose up -d --build to rebuild images after modifying the Dockerfile or related configurations.

5. Access the application:
   • App: http://localhost:8080
   • phpMyAdmin: http://localhost:8081

Configuring the Database:

The default database name is slim_mvc. To use a different database name:

1. Update docker-compose.yml:

2. Update config/env.docker.php:

3. Rebuild containers: docker-compose up -d --build

Importing Database Schema:

To automatically import a database schema when the container starts:

1. Place your .sql file(s) in the docker/init-db/ folder
2. Start the containers: docker-compose up -d

The SQL files will be executed automatically on first container creation. If you have multiple files, they run in alphabetical order (e.g., 01-schema.sql, 02-data.sql).

To re-import the schema, remove the database volume and restart:

Common Commands:

Working with Multiple Projects:

If you run one project at a time, no configuration changes are needed. Simply stop one project before starting another:

If you need to run multiple projects simultaneously, change the port numbers in docker-compose.yml to avoid conflicts:

Option 3: Manual Installation

1. Download this repository as a .zip file.
2. Extract the downloaded slim-mvc-main.zip file locally.
3. Copy the slim-mvc-main folder into your web server's document root (i.e., htdocs).
4. Rename the slim-mvc-main folder to [project_name]-app (for example, worldcup-app).
5. Open your [project_name]-app folder in VS Code.
6. Install the project dependencies by running composer. If you are using Wampoon, open a terminal window in VS Code (hit ) then run .\composer.bat update
   • If you are not using Wampoon to develop your app, just run composer from the command line.
7. In the config folder, make a copy of env.example.php and rename it to env.php.
8. Adjust your database credentials (see below).

** You can always clone this repository. However, if you do, you need to remove the **hidden directory before you copy this template over to

How Do I Configure My Database Connection?

Follow the outlined instructions in config/env.example.php

• Change the value of the database variable to reflect the name of the database to be used by your slim app.
• You may also want to change the connection credentials in that file.

How do I Use Composer with Wampoon?

To install or update your project dependencies deployed on Wampoon, use the composer.bat script as follows:

On Using Environment Variables

Sensitive information used in app such as your database credentials, API key, etc. MUST not be pushed into your Git repo.

Do not use .env files for storing environment specific application settings/configurations. Dotenv is not meant to be used in production

Just Google: "DB_PASSWORD" filetype:env Alternatively, you can visit the following link: Google env search

Instead, follow the instructions that are detailed in config/env.example.php

Project Structure

Here's how everything is organized:

Quick Development Tips

Adding Routes

Routes are defined in the app/Routes/ directory. Check out the existing route files to see how it's done.

Creating Controllers

Controllers go in app/Controllers/. They should extend the base controller class and follow PSR-4 autoloading.

Views and Templates

Templates are stored in app/Views/. The template engine is already configured and ready to use.

Configuration

App configuration lives in config/. Modify these files to customize your application settings.

Logging

Logs are written to the var/logs/ directory. Use the injected logger in your controllers to track what's happening.

Need Help?

• Check out the Slim documentation for framework-specific questions.
• Look at the example controllers and routes to see how everything fits together.
• The code is pretty well commented, so don't hesitate to explore it well.
