PHP ermittelt Länder, Provinzen, Städte und Umgebungsdaten basierend auf geografischen Koordinaten

Funktion: Wenn die App die geografischen Koordinaten des Benutzers erhält, kann sie anhand der Koordinaten das Land, die Provinz, die Stadt und die Umgebungsdaten des Benutzers ermitteln.

Prinzip: Basierend auf BaiduGeocoding API Sie müssen sich zuerst als Baidu-Entwickler registrieren und dann Baidu AK (Schlüssel)
Geocoding.class.php
