How to use Amap API in PHP to implement map location search

In recent years, with the rapid development of the Internet, map applications have become an indispensable part of people's lives. As China's leading map application, Amap has powerful map functions and rich API interfaces, making it a favorite map choice for many developers. This article will introduce how to use the PHP language and combine it with the Amap API to implement the search function around the location of the map in the web page.

1. Create an AMAP developer account

First, we need to go to the [Amap Developer Platform](https://lbs.amap.com /dev/index), register a developer account, create a new application, and obtain the API key for subsequent use.

2. Introduce Amap API

Introduce the Javascript library file of Amap API at the head of the php file. The specific code is as follows:

3. Create a map object

Add the following Javascript code in the php code to create a map object and display the map in the specified container middle.

In the code, we specify a div element with the id map as the container for map display, and set the zoom level and the coordinates of the center point. These parameters can be adjusted according to actual needs.

4. Add the search function around the location

The following is a sample code for implementing the search function around the location on the map.

In the code, we first create a custom search control and specify the mark icon and coordinates of the search results. Then, by listening to click events on the map, the click coordinates are obtained, and the PlaceSearch plug-in of Amap is called to conduct a search around the location. Search results are displayed as markers on the map.

It is worth noting that the parameters in the code can be adjusted according to actual needs, such as search keywords, search radius, city, etc.

Through the above steps, we can use the Amap API in the php file to implement the location search function around the map. In this way, users can use the web page we developed to conveniently search for places of interest on the map.
