How to use PHP to display Amap on a web page
In recent years, map services have played an increasingly important role in web development. Among them, Amap, as the leading map service provider in China, has performed well in terms of ease of use and rich functions. This article will introduce how to use PHP to display Amap on a web page, and attach code examples for readers' reference.
First of all, we need to register and apply for an API key on the Amap open platform. After successful registration, we can obtain a unique API key to call the Amap interface in code.
In web pages, we commonly use JavaScript to call the Amap interface, but the same function can also be achieved through PHP. Below is a simple sample code that shows how to use PHP to display the Amap map on a web page.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>使用PHP显示高德地图</title>
<style>
#map {
width: 800px;
height: 600px;
}
</style>
</head>
<body>
<div id="map"></div>
<script src="https://webapi.amap.com/maps?v=1.4.15&key=你的API密钥"></script>
<script>
var map = new AMap.Map('map', {
center: [116.397428, 39.90923],
zoom: 13
});
// 在地图上添加标记
var marker = new AMap.Marker({
position: [116.397428, 39.90923],
map: map
});
</script>
</body>
</html>The above code demonstrates how to create a map of 800px * 600px size on a web page and add a marker point on the map. You need to replace your API key in the code with the API key you applied for on the Amap open platform.
To display the Amap map in a web page, we need to introduce the JavaScript SDK of the Amap map and create an AMap.Map object in the code to instantiate the map and set the initial Center point and zoom level. To add a marker point through AMap.Marker, you can set the location of the marker point and the map on which it will be displayed.
In addition to displaying maps and marked points, Amap also provides a wealth of functions and API interfaces for searching locations, route planning, positioning, and more. Readers can learn more about the use of functions and interfaces by consulting the documentation of the Amap open platform.
To sum up, by calling the Amap API through PHP, we can easily display the map and add marker points on the web page. I hope that the sample code in this article can help readers and allow you to better utilize the powerful functions of Amap in web development.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
