Setting Up a PHP Tile Server

Installation, Folder Structure, and Integration with osmdroid or Leaflet with .mbtiles

Before we begin, make sure you have the following prerequisites in place:

  • Web Server: Choose a web server like Apache or Nginx to host your PHP application.
  • PHP: Install PHP on your server
  • Database: Set up a database
  • Mobile Development Environment for osmdroid

Step 1: Choose a PHP Tile Server Library

For this guide, we’ll use the Leaflet library along with Leaflet.TileLayer.PHP.

Step 2: Installation of PHP Tile Server Library

Folder Structure:

|-- assets
|   |-- css
|   |   |-- leaflet.css
|   |-- js
|       |-- leaflet.js
|-- scripts
|   |-- generate_tile.php
|-- vendor
|   |-- leaflet
|   |   |-- ...
|   |-- leaflet-tilelayer-php
|       |-- ...
|-- .gitignore
|-- index.php
|-- config.php
|-- mbtiles
|   |-- your_map.mbtiles
  • project-root: The main directory of your PHP tile server project.
  • assets: Holds subdirectories for CSS and JS files. Store Leaflet-related styles and scripts here.
  • scripts: Contains PHP scripts for generating and serving map tiles (e.g., generate_tile.php).
  • vendor: Directory for third-party libraries, including Leaflet and Leaflet.TileLayer.PHP.
  • .gitignore: A file specifying files and directories to be ignored by version control.
  • index.php: The main entry point for your PHP tile server application.
  • config.php: Configuration file for storing database credentials and settings.
  • mbtiles: A directory to store your .mbtiles files, which are efficient for map storage.

Step 3: Calling the Map from osmdroid (Android) and Leaflet (Web):

Calling from osmdroid (Android):

Use the following code snippet to call the map from osmdroid in your Android application:

// Assuming you have a MapView in your layout with id "mapView"
MapView mapView = (MapView) findViewById(R.id.mapView);
mapView.setTileSource(new XYTileSource("MyTileServer", null, 1, 18, 256, ".png", new String[]{}));

Replace "MyTileServer" with the URL of your PHP tile server.

Calling from Leaflet (Web):

In your HTML file, include the Leaflet library and initialize the map with your PHP tile server:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PHP Tile Server Map</title>
    <link rel="stylesheet" href="assets/css/leaflet.css">
    <script src="assets/js/leaflet.js"></script>
    <div id="map" style="height: 500px;"></div>
        var map = L.map('map').setView([0, 0], 2); // Set your initial coordinates and zoom

Step 4: Using .mbtiles Files:

If you have .mbtiles files for your maps, consider using the mbtiles-php library. Import the library into your project and modify the generate_tile.php script to handle .mbtiles file rendering.

With these steps, you’re now equipped to set up a PHP tile server, maintain a structured project folder, and seamlessly integrate maps into both Android applications using osmdroid and web applications using Leaflet. The use of .mbtiles files ensures efficient map storage and retrieval, enhancing the overall performance of your dynamic map solution. Happy mapping!
