I think the error in your request URL. Please check below code. 

$url = "https://geocoder.api.here.com/6.2/geocode.json?app_id=NT2iR8TD1kAeCxERIow8&app_code=-r9pZGDuz6G5NWToLaCSUQ&searchtext=3891 Delwood Drive, Powell, OH, United States";
$url = str_replace(" ","%20",$url);
$json = @file_get_contents($url);
$details = json_decode($json, TRUE);
print_r($details);

Detects Your Problem

If you read the $http_response_header array (generated by file_get_contents() call), you'd find out that you got a "400 Bad Request" response and thus got nothing. So something must have gone wrong with your URL.

After a brief inspection, I think perhaps its your "searchtext" parameter that's blocking you. For starter, valid URL query don't usually have spaces in it. Probably why the API server says that you're a "Bad Request".

Normally, you need to properly escape the URL query string to have a proper URL. Modern browsers are very good at translating it for you seamlessly and automatically so you might not have this problem by using the URL directly in browsers.

Solution

Let's put this theory to a test. We'll use http_build_query() to escape your query query parameters:

(For privacy reason, the parameters are modified. Please substitute the query variables)

$query = http_build_query([
  'app_id' => 'your-app-id',
  'app_code' => 'your-app-code',
  'searchtext' => '123 Some Address',
]);
$url = 'https://geocoder.api.here.com/6.2/geocode.json?' . $query;
$json = file_get_contents($url);
$details = json_decode($json, TRUE);

var_dump($details);

I seem to get proper decoded response now. Try it yourself.
