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

This article mainly introduces the implementation method of PHP using Baidu Map to obtain the longitude and latitude of the specified address coordinates.

In the previous article [PHP uses Baidu Map to obtain the specified address coordinates: Create AK], I have introduced to you how to create an AK (api key) in the Baidu Map open platform. method. So this article will use this example to continue to explain to you the specific method of using Baidu Map to obtain longitude and latitude in PHP.

Of course, if you have read the previous articles about using Tencent Maps to obtain latitude and longitude, it will be easier to understand the content of this section. Friends in need can choose to refer to

[PHP uses Tencent Map to obtain the specified address coordinates: create key][PHP uses Tencent Map to obtain the specified address coordinates: longitude and latitude]This Two articles.

The code example for PHP to use Baidu Map to obtain longitude and latitude is as follows:

result->location->lng; $lat = $json_data->result->location->lat; echo '经度：'.$lng;// 纬度 echo "
"; echo '纬度：'.$lat;// 经度 /** * 腾讯地图获取的经纬度 * 经度:117.22715 纬度:31.820431 * * 百度地图获取的经纬度* 经度：117.24110601945 纬度：31.817876972112 */

The main thing to note in the above code is the parameters in the url we defined, which actually include address and output method ( Here we are outputting it in json format), and then there is the AK we created before (api key, here we are using the browser-side AK).

Then obtain the latitude and longitude through the above method, the result is as follows:

As you can see from the picture, we successfully obtained the latitude and longitude.

I believe you have already discovered something. In the comments in the above code, we also wrote down the longitude and latitude previously obtained using Tencent Maps. Comparing the two, we can find that the longitude and latitude obtained for the same address are basically the same. , but the accuracy is different. Obviously, the accuracy of Baidu Map is higher.

This article is aboutPHP using Baidu Map to obtain the longitude and latitude of the specified address coordinates. It is also very simple and easy to understand. I hope it will be helpful to friends in need. !
