Customizing Baidu Map Styles with PHP and Baidu Maps API

Introduction: Baidu Maps API provides map functions for websites and apps; this guide shows how to customize map styles using PHP.

Step 1: Apply for an API key – Register on Baidu Open Platform, create an application, and obtain the key.

Step 2: Include the Baidu Maps library – Download the library from the Baidu developer site and place it in your project.

Step 3: Create a map container – Add an HTML <div id="map" style="width:100%; height:500px;"></div> to hold the map.

Step 4: Initialize the map object – In PHP, require the library and create a BMap instance, then set the API key:

<?php
require_once 'path_to_baidumap_api/BMap.php';
$map = new BMap();
$map->set_ak('your_api_key');

Step 5: Set the map style – Define a JSON style string and call $map->setMapStyle($styleJson); :

<?php
$styleJson = '{
"style": "bluish",
"feature": {
"road": {"show": false},
"building": {"show": false},
"poi": {"show": false}
}
}';
$map->setMapStyle($styleJson);

Step 6: Render the map – Output the map in the container with $map->renderMap('map'); .

Conclusion: By following these six steps—obtaining a key, loading the library, creating a container, initializing the map, applying a style, and rendering—you can customize Baidu Maps in PHP projects.
