# Tile Proxy PHP: a simple caching-Proxy for WMTS Servers
|
|
|
|
This software should make it simple to use pre-rendered map tiles in your own projects, without flooding too many tiles-servers.
|
|
|
|
## Requirements:
|
|
|
|
- **Apache** webserver (with **_mod_rewrite_** / **_.htaccess_** support / **_php_curl_** extension)
|
|
- **PHP 5.3+**
|
|
|
|
## Installation:
|
|
|
|
Download project files and upload it into your web hosting of your choice.
|
|
|
|
Open the **"test.html"** file within your browser, your proxy server should display you a simple slippy maps rendering default Open Street Map tiles.
|
|
Or test directly in your browser with a tile URL such as: http://www.example.com/tiles/15/17024/10792.png
|
|
|
|
**NB.** Remeber to check your web server folder permissions: **777** or **755**

|
## How to use
|
|
|
|
1. **edit the default "config.php"**
|
|
```php
|
|
/**
|
|
* Whitelist of supported tile servers
|
|
*
|
|
* @link https://wiki.openstreetmap.org/wiki/Tile_servers
|
|
*
|
|
* @var array
|
|
*/
|
|
$tiles_config['servers'] = array(
|
|
'osm' => 'https://{switch:a,b,c}.tile.openstreetmap.org/{z}/{x}/{y}.png',
|
|
'otm' => 'https://{switch:a,b,c}.tile.opentopomap.org/{z}/{x}/{y}.png',
|
|
// ADD: more services here.
|
|
);
|
|
|
|
/**
|
|
* Cached Bounding Box
|
|
*
|
|
* BBox = left, bottom, right, top
|
|
* BBox = min_lng, min_lat, max_lng, max_lat
|
|
*
|
|
* Planet: bbox = '-180,-90,180,90'
|
|
*
|
|
* @link https://openmaptiles.com/extracts/
|
|
*
|
|
* @var string
|
|
*/
|
|
// CHANGE: bounding box cache-area to fit your own needs
|
|
$tiles_config['bbox'] = '6.602696,35.07638,19.12499,47.10169'; // CHANGE: bbox tiles (Italy) are cached, others are proxied!
|
|
|
|
/**
|
|
* Cache timeout in seconds
|
|
*
|
|
* 12 hour = 43200 sec
|
|
* 1 day = 86400 sec
|
|
* 1 month = 2629800 sec
|
|
*
|
|
* @var int
|
|
*/
|
|
$tiles_config['ttl'] = 86400;
|
|
|
|
/**
|
|
* Custom Proxy Server headers
|
|
*
|
|
* @var string
|
|
*/
|
|
$tiles_config['headers'] = array(
|
|
'Access-Control-Allow-Origin:' => '*',
|
|
);
|
|
```
|
|
|
|
2. **create your first simple “tile-proxy-php” slippy map**
|
|
|
|
a. **_include CSS & JavaScript_**
|
|
```html
|
|
<head>
|
|
...
|
|
<style>html, body, #map { width: 100%; height: 100%; margin: 0; padding: 0; }</style>
|
|
<link rel="stylesheet" href="https://unpkg.com/leaflet@1.3.4/dist/leaflet.css" />
|
|
<script src="https://unpkg.com/leaflet@1.3.4/dist/leaflet.js"></script>
|
|
...
|
|
</head>
|
|
```
|
|
|
|
a. **_choose the div container used for the slippy map_**
|
|
```html
|
|
<body>
|
|
...
|
|
<div id="map"></div>
|
|
...
|
|
</body>
|
|
```
|
|
b. **_create the slippy map_**
|
|
```html
|
|
<script>
|
|
var map = L.map('map').setView([0, 0], 0);
|
|
|
|
var proxy_url = 'http://example.com/tiles/{id}/{z}/{x}/{y}.png'; // CHANGE: "http://example.com/tiles" to fit your own needs
|
|
var tms_id = 'otm';
|
|
|
|
var tileLayer = L.tileLayer(proxy_url, {
|
|
attribution: 'map data: © <a href="https://openstreetmap.org/copyright">OpenStreetMap</a> contributors, ' +
|
|
'<a href="http://viewfinderpanoramas.org">SRTM</a> | ' +

|
'map style: © <a href="https://opentopomap.org">OpenTopoMap</a> ' +
|
|
'(<a href="https://creativecommons.org/licenses/by-sa/3.0/">CC-BY-SA</a>), ',
|
|
id: tms_id
|
|
});
|
|
tileLayer.addTo(map);
