PHP uses Tencent Map to obtain the coordinates of the specified address: longitude and latitude (image, text + video)

This article mainly introduces to you the specific method of PHP using Tencent Map to obtain the coordinates of a specified address.

In the previous article [How to create a key using Tencent Map to obtain the specified address coordinates using PHP], we have already introduced to you how to apply to create a key (developer key). So below we will combine specific code examples to introduce in detail how PHP uses Tencent Maps to obtain specified coordinates, that is, longitude and latitude.

<?php
// 腾讯地图
$address = &#39;合肥政务区潜山路888号&#39;;

$url = "http://apis.map.qq.com/ws/geocoder/v1/?address=$address&key=QAKBZ-Y4OC2-4H7UY-CYDNW-NEYV2-K2FSN";
// 初始url会话
$ch = curl_init();
//  设置url传输选项
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// 执行url会话
$data = curl_exec($ch);
$map = json_decode($data);
var_dump($map);
$location = $map->result->location;
echo "经度:".$location->lng."<br/>";// 经度
echo "纬度:".$location->lat."<br/>";// 纬度

Here we define an address $address and a link $url. It should be noted that there are two important parameters in this link, one is the defined $address, and the other is the key created by ourselves (development or key). Then initialize the cURL session through the curl_init function in PHP, and use the curl_setopt function to set the cURL transfer options. Then use the curl_exec function to execute the cURL session.

Then we convert the obtained url data into json format through the json_decode function.

Finally we can get the corresponding location coordinates.

Access through the browser, the result is as follows:

As shown in the figure, we obtain the longitude and latitude of the specified address.
