У меня есть PHP-скрипт, который пытается читать и анализировать строки JSON, возвращаемые из API геокодера Google. Сценарий отлично работает для большинства адресов, но в некоторых случаях он сталкивается с проблемами, когда Google Geocoder API возвращает несколько результатов для данного адреса.
Это мой код:
$mGeoFile = fopen("http://maps.googleapis.com/maps/api/geocode/json?address=" . str_replace(" ", "+", $mAddress0) . "&sensor=false", "r");
$mGeoFileJSON = fread($mGeoFile, 10000);
fclose($mGeoFile);
$mGeocode_array = json_decode($mGeoFileJSON, true);
var_dump($mGeocode_array);
echo "<br />";
var_dump($mGeocode_array['results'][0]['geometry']['location']);
Что печатает это для "115 Chestnut Street Upton, MA" (передается в $ mAddress0):
array(2) { ["status"]=> string(2) "OK" ["results"]=> array(1) { [0]=> array(4) { ["types"]=> array(1) { [0]=> string(14) "street_address" } ["formatted_address"]=> string(37) "115 Chestnut St, Upton, MA 01568, USA" ["address_components"]=> array(8) { [0]=> array(3) { ["long_name"]=> string(3) "115" ["short_name"]=> string(3) "115" ["types"]=> array(1) { [0]=> string(13) "street_number" } } [1]=> array(3) { ["long_name"]=> string(11) "Chestnut St" ["short_name"]=> string(11) "Chestnut St" ["types"]=> array(1) { [0]=> string(5) "route" } } [2]=> array(3) { ["long_name"]=> string(5) "Upton" ["short_name"]=> string(5) "Upton" ["types"]=> array(2) { [0]=> string(8) "locality" [1]=> string(9) "political" } } [3]=> array(3) { ["long_name"]=> string(5) "Upton" ["short_name"]=> string(5) "Upton" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_3" [1]=> string(9) "political" } } [4]=> array(3) { ["long_name"]=> string(9) "Worcester" ["short_name"]=> string(9) "Worcester" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_2" [1]=> string(9) "political" } } [5]=> array(3) { ["long_name"]=> string(13) "Massachusetts" ["short_name"]=> string(2) "MA" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_1" [1]=> string(9) "political" } } [6]=> array(3) { ["long_name"]=> string(13) "United States" ["short_name"]=> string(2) "US" ["types"]=> array(2) { [0]=> string(7) "country" [1]=> string(9) "political" } } [7]=> array(3) { ["long_name"]=> string(5) "01568" ["short_name"]=> string(5) "01568" ["types"]=> array(1) { [0]=> string(11) "postal_code" } } } ["geometry"]=> array(4) { ["location"]=> array(2) { ["lat"]=> float(42.1476896) ["lng"]=> float(-71.5863099) } ["location_type"]=> string(18) "RANGE_INTERPOLATED" ["viewport"]=> array(2) { ["southwest"]=> array(2) { ["lat"]=> float(42.1445379) ["lng"]=> float(-71.5894495) } ["northeast"]=> array(2) { ["lat"]=> float(42.1508332) ["lng"]=> float(-71.5831542) } } ["bounds"]=> array(2) { ["southwest"]=> array(2) { ["lat"]=> float(42.1476815) ["lng"]=> float(-71.5863099) } ["northeast"]=> array(2) { ["lat"]=> float(42.1476896) ["lng"]=> float(-71.5862938) } } } } } }
array(2) { ["lat"]=> float(42.1476896) ["lng"]=> float(-71.5863099) }
Также геокодер возвращает следующую строку JSON для «115 Chestnut Street Upton, MA»

И мой скрипт возвращает:

Есть идеи, что может происходить? Спасибо!
