谷歌地图api foreach和呼应最近的地铁站名称

Question

I am trying to get the contents "name" of the nearest subway stations via the google maps api.

But i'm getting no results for some reason.

any ideas?

<?
$stations = file_get_contents('https://maps.googleapis.com/maps/api/place/nearbysearch/json?key=XXXXX&location=51.517238,-0.0731695&rankby=distance&type=subway_station');
$stations = json_decode($stations);

foreach ($stations as $data)
    {


echo  $data->results->name;

    }?>

**PRINT / VARDUMP OF $STATIONS **

Answer 1

Running print_r($stations); returns an error:

stdClass Object ( [error_message] => The provided API key is invalid. [html_attributions] => Array ( ) [results] => Array ( ) [status] => REQUEST_DENIED )

It looks like this issue has been seen before, but wasn't asked in a way that could have been answered without printing the stations variable the way I did. Here is a link to the answer that refers to a required business account with Google:

google maps api, The provided API key is invalid

Also, referring to the Google documentation, it looks like your URL may be formatted incorrectly:

https://developers.google.com/maps/documentation/javascript/error-messages

Please let me know if this helps.

EDIT:

Here is another answer that might help:

Google Places API Web Services API Key Invalid

You can replace `key=XXXXX' with a key generated following the instructions at https://developers.google.com/places/web-service/get-api-key

EDIT:

That is a log of data to parse, but it looks to me that the $data->results array should be the one you are iterating through. Have you tried changing the context to:

<?php
$stations = file_get_contents('https://maps.googleapis.com/maps/api/place/nearbysearch/json?key=XXXXX&location=51.517238,-0.0731695&rankby=distance&type=subway_station');
$stations = json_decode($stations);
$stations = $stations->results;
foreach ($stations as $data)
    {

echo  $data->name;

    }

Honestly, someone with an API key might do better at answering this question, but that's my best guess without having the data in a parsable format to read back in. Not saying it can be done, just take a lot of work, and I think this should work from how I read the var dump.

FINAL EDIT

I can confirm the above code works. The results when printed with echo <br>; in the for loop will result in:

Aldgate East
Aldgate Station
Liverpool Street
Tower Hill
Whitechapel
Moorgate Station
Monument Station
Bank Underground Station
Old Street

Cannon Street Underground Station
