Use Baidu Map API to realize indoor map display and navigation in PHP

With the continuous advancement and development of science and technology, indoor navigation systems have attracted more and more attention, and Baidu Map is the most commonly used in China. One of the map services, it provides a rich API interface for developers to use. In this article, we will explore how to use PHP combined with Baidu Map API to realize indoor map display and navigation.

1. Environment preparation
Before we start, we need to ensure that PHP has been installed in the environment, have a Baidu Maps developer account, and register an application to obtain an API key in order to complete Baidu Map API calls.

2. Introduction of Baidu Map API
First, we need to introduce the JavaScript file of Baidu Map API into the PHP file. Assuming that our file is called "indoor-map.php", we can add the following code in the header:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>室内地图展示与导航</title>
    <style type="text/css">
        #map {
            width: 100%;
            height: 500px;
        }
    </style>
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的API密钥"></script>
</head>
<body>
    <div id="map"></div>
</body>
</html>

It should be noted that "your API key" in the above code needs to be replaced by your The key I obtained from the Baidu Map Developer Platform.

3. Display indoor map
After the page is loaded, we can display the indoor map by calling the relevant methods of Baidu Map API. Add the following code in the tag of the page:

<script type="text/javascript">
    // 创建地图实例
    var map = new BMap.Map("map");
    // 设定地图的中心点和缩放级别
    var point = new BMap.Point(116.404, 39.915);
    map.centerAndZoom(point, 17);
    // 启用室内地图控件
    map.enableIndoor();

    // 展示室内地图
    var indoorManager = new BMapLib.IndoorManager(map);
    indoorManager.enableIndoorMapControl();

    // 添加室内POI图层
    var poiLayer = new BMap.IndoorPOI(map);
    poiLayer.enable3DBuilding();

    // 加载室内地图
    indoorManager.setMapCallback(function(result) {
        if (result.error === 0) {
            indoorManager.show(result.floor_index);
        }
    });
    indoorManager.init("室内地图ID");
</script>

Among them, the "indoor map ID" in the code needs to be replaced with the ID of the specific indoor map you are using.

4. Indoor Navigation
To implement indoor navigation, we need to use the path planning function of Baidu Map API. Add the following code in the
