Php-Slim with Leaflet Map

Title: Building a SlimPHP Application with Leaflet.js Mapping on Fedora Linux


Introduction

SlimPHP is a lightweight PHP framework that makes it easy to build web applications, and Leaflet.js is a powerful JavaScript library for interactive maps. Together, they provide a robust solution for creating web applications with mapping capabilities. In this guide, we’ll walk you through setting up a SlimPHP application with Leaflet.js for mapping on Fedora Linux.


Step 1: Install PHP and Composer

First, ensure you have PHP and Composer installed on your Fedora system. Open a terminal and run:

sudo dnf install -y php php-cli php-common php-mbstring php-xml
sudo dnf install -y composer

Verify the installations:

php --version
composer --version

Step 2: Create a New SlimPHP Project

Create a new directory for your SlimPHP project and navigate into it:

mkdir my-slim-map-app
cd my-slim-map-app

Use Composer to create a new SlimPHP project:

composer require slim/slim "^4.0"
composer require slim/psr7
composer require nyholm/psr7
composer require slim/twig-view

Step 3: Set Up the Project Structure

Create the following directory structure within your project:

my-slim-map-app/
├── public/
│   └── index.php
├── templates/
│   └── map.twig
└── src/
    └── dependencies.php

Step 4: Configure SlimPHP with Twig

Edit the index.php file in the public directory:

<?php

require __DIR__ . '/../vendor/autoload.php';

use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;

$app = AppFactory::create();

$twig = Twig::create('../templates', ['cache' => false]);
$app->add(TwigMiddleware::createFromContainer($app, Twig::class));

$app->get('/', function (Request $request, Response $response, $args) {
    $view = Twig::fromRequest($request);
    return $view->render($response, 'map.twig');
});

$app->run();

Step 5: Create a Twig Template for the Map

Create a map.twig file in the templates directory with the following content:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Leaflet Map with SlimPHP</title>
    <link rel="stylesheet" href="https://unpkg.com/leaflet/dist/leaflet.css" />
    <style>
        #map {
            height: 100vh;
        }
    </style>
</head>
<body>
    <div id="map"></div>
    <script src="https://unpkg.com/leaflet/dist/leaflet.js"></script>
    <script>
        var map = L.map('map').setView([51.505, -0.09], 13);

        L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
        }).addTo(map);

        L.marker([51.5, -0.09]).addTo(map)
            .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')
            .openPopup();
    </script>
</body>
</html>

Step 6: Serve Your Application

To serve your SlimPHP application, use the built-in PHP server. Navigate to your project directory and run:

php -S localhost:8080 -t public

Open your web browser and visit http://localhost:8080. You should see a Leaflet map displayed.


Step 7: Add More Features to Your Map

You can extend the functionality of your map by adding more markers, popups, and layers. For example, update map.twig to include additional features:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Leaflet Map with SlimPHP</title>
    <link rel="stylesheet" href="https://unpkg.com/leaflet/dist/leaflet.css" />
    <style>
        #map {
            height: 100vh;
        }
    </style>
</head>
<body>
    <div id="map"></div>
    <script src="https://unpkg.com/leaflet/dist/leaflet.js"></script>
    <script>
        var map = L.map('map').setView([51.505, -0.09], 13);

        L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            attribution: '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'
        }).addTo(map);

        var marker = L.marker([51.5, -0.09]).addTo(map)
            .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')
            .openPopup();

        var circle = L.circle([51.508, -0.11], {
            color: 'red',
            fillColor: '#f03',
            fillOpacity: 0.5,
            radius: 500
        }).addTo(map).bindPopup('I am a circle.');

        var polygon = L.polygon([
            [51.509, -0.08],
            [51.503, -0.06],
            [51.51, -0.047]
        ]).addTo(map).bindPopup('I am a polygon.');
    </script>
</body>
</html>

Conclusion

You have successfully set up a SlimPHP application with Leaflet.js for interactive mapping on Fedora Linux. This setup provides a robust foundation for building web applications with dynamic maps. Feel free to expand your application by adding more routes, templates, and Leaflet features. Happy mapping!
