Question

有人可以帮助我从数据库中上传经纬度的地址文本吗？另外，我需要将地址及其相应的坐标重新插入到de数据库中。

<?php    
// Opens a connection to a MySQL server

$con = new mysqli($servername, $username, $password, $database);


$result = mysqli_query($con,'SELECT * FROM table_name ORDER BY id DESC');


while ($row = @mysqli_fetch_assoc($result)){

  $latitude=  $row['latitude']. '  ';
  $longitude=  $row['longitude']. '  ';

}

?>

是否有一种方法可以获取地址并在一段时间内插入它，以便它获取地址并立即发送回去？任何帮助，谢谢！

您可以使用google maps api，以前它们允许匿名访问其API，但现在您必须获取一个API密钥。 https://developers.google.com/maps/documentation/geocoding/intro#Limits

<?php    
// Opens a connection to a MySQL server

$con = new mysqli($servername, $username, $password, $database);


$result = mysqli_query($con,'SELECT * FROM table_name ORDER BY id DESC');


while ($row = @mysqli_fetch_assoc($result)){

  $latitude=  $row['latitude']. '  ';
  $longitude=  $row['longitude']. '  ';

  $geolocation = $latitude.','.$longitude;

  // be sure to replace API key
  $request = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.$geolocation.'&sensor=false'.'key=YOUR_API_KEY'; 

  // retrieve data from url, GET REQUEST
  $file_contents = file_get_contents($request);

  // decode json object
  $json_decode = json_decode($file_contents);

  // return the json object of the first record, navigate to the address from here
  var_dump($json_decode);
}

?>

您要执行的操作称为反向地理编码，即将地图上的位置转换为人类可读的地址。

如果您使用JavaScript进行此操作，则需要纬度和经度（您已经提到过）和API key。有了这些，您基本上可以使用下面的URL以及所需的经纬度和API密钥进行GET请求。

const lat = 'LAT_COORDS_STRING';
const lng = 'LNG_COORDS_STRING';
const apiKey = 'MY_API_KEY_STRING'

const url = `https://maps.googleapis.com/maps/api/geocode/json?latlng=${lat},${lng}&key=${apiKey}`;

上面的查询将返回一个JSON（请参见下文），您可以解析并提取所需的信息（也许字段formatted_address是您所需要的）。
