我是JSON和php的新手.我需要在调用json_decode()之后从以下json中获取 lat 和 lng .但是我不知道如何访问它们.

Im new to JSON and php. I need to grab the lat and lng from the following json after calling json_decode(). But I don't know how to access them.

{ "status": "OK", "results": [ { "types": [ "street_address" ], "formatted_address": "1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA", "address_components": [ { "long_name": "1600", "short_name": "1600", "types": [ "street_number" ] }, { "long_name": "Amphitheatre Pkwy", "short_name": "Amphitheatre Pkwy", "types": [ "route" ] }, { "long_name": "Mountain View", "short_name": "Mountain View", "types": [ "locality", "political" ] }, { "long_name": "California", "short_name": "CA", "types": [ "administrative_area_level_1", "political" ] }, { "long_name": "United States", "short_name": "US", "types": [ "country", "political" ] }, { "long_name": "94043", "short_name": "94043", "types": [ "postal_code" ] } ], "geometry": { "location": { "lat": 37.4219720, "lng": -122.0841430 }, "location_type": "ROOFTOP", "viewport": { "southwest": { "lat": 37.4188244, "lng": -122.0872906 }, "northeast": { "lat": 37.4251196, "lng": -122.0809954 } } } } ] }

推荐答案

在PHP中，JSON对象解码为对象，而数组解码为数组:

In PHP, JSON objects decode to objects, and arrays to arrays:

$data->results[0]->geometry->location->lat $data->results[0]->geometry->location->lng
