Php obtains the country, province, city, and surrounding data types based on geographic coordinates.

: This article describes how to use php to obtain data from countries, provinces, cities, and surrounding areas based on geographical coordinates. For more information about PHP tutorials, see. Function: when the App obtains the geographical coordinates of a user, it can know the data of the user in that country, province, city, and surrounding area based on the coordinates.

Principle: based on the Baidu Geocoding API, you need to register a Baidu developer first, and then apply for a Baidu AK (key)
Geocoding. class. php

  $ Ak, 'location' => implode (',', array ($ latitude, $ longpolling), 'pois '=> $ pois, 'output' => 'json'); // request Baidu api $ response = self: toCurl (self: API, $ param); $ result = array (); if ($ response) {$ result = json_decode ($ response, true);} return $ result ;} /*** use curl to call Baidu Geocoding API * @ param String $ url request address * @ param Array $ param request parameter * @ return JSON */privatestaticfunctiontoCurl ($ url, $ param = array ()) {$ Ch = curl_init (); if (substr ($ url, 0,5) = 'https') {curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, false ); // skip the certificate check curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, true); // check whether the SSL encryption algorithm exists from the certificate} curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt ($ ch, CURLOPT_URL, $ url); curl_setopt ($ ch, CURLOPT_POST, true); curl_setopt ($ ch, CURLOPT_POSTFIELDS, http_build_query ($ param )); $ response = curl_exec ($ ch); if ($ Error = curl_error ($ ch) {returnfalse;} curl_close ($ ch); return $ response ;}}?>

Demo. php

  '; Print_r ($ result); echo'

';?>

Return example:

Array ([status] => 0 [result] => Array ([location] => Array ([lng] => 113.32778195925 [lat] => 23.137201991056) [formatted_address] => No. 35, Xiheng Street, sports, Tianhe district, Guangzhou, Guangdong, China [business] => Tianhe city, sports center, shahe [addressComponent] => Array ([city] => Guangzhou [country] => China [direction] => nearby [distance] => 14 [district] => Tianhe district [province] => Guangdong [street] => sports West Heng street [street_number] => 35 [country_code] => 0) [poiRegions] => Array () [sematic_description] => 58 meters north of Hongyi building [cityCode] => 257 ))
