How to make oauth2 for here map API in php

To make oauth2 authentication in PHP for here map you need bellow credentials:-

1) here.access.key.id

2) here.access.key.secret

Now use below code snippet to create an access token

$timer = (string) time();
$grant_type = 'client_credentials';
$oauth_consumer_key = 'here.access.key.id';
$oauth_nonce = uniqid(mt_rand(1, 1000));
$oauth_signature_method = 'HMAC-SHA256';
$oauth_timestamp = $timer;
$oauth_version = '1.0';
$url = 'https://account.api.here.com/oauth2/token';
$access_key_secret = "here.access.key.secret";

$parameter_string = 'grant_type='.$grant_type;
$parameter_string .= '&oauth_consumer_key='.$oauth_consumer_key;
$parameter_string .= '&oauth_nonce='.$oauth_nonce;
$parameter_string .= '&oauth_signature_method='.$oauth_signature_method;
$parameter_string .= '&oauth_timestamp='.$oauth_timestamp;
$parameter_string .= '&oauth_version='.$oauth_version;
$encoded_parameter_string = urlencode($parameter_string);

$encoded_base_string = 'POST'.'&'.urlencode($url).'&'.$encoded_parameter_string;

$signing_key = $access_key_secret.'&';

$signature = hash_hmac('SHA256', $encoded_base_string, $signing_key, true);

$encodedSignature = urlencode(base64_encode($signature));

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://account.api.here.com/oauth2/token',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => 'grant_type=client_credentials',
  CURLOPT_HTTPHEADER => array(
    'Authorization: OAuth oauth_consumer_key="'.$oauth_consumer_key.'",oauth_signature_method="HMAC-SHA256",oauth_timestamp="'.$oauth_timestamp.'",oauth_nonce="'.$oauth_nonce.'",oauth_version="1.0",oauth_signature="'.$encodedSignature.'"',
    'Content-Type: application/x-www-form-urlencoded'
  ),
));

$response = curl_exec($curl);
curl_close($curl);

echo $response;

Now you have a bearer access token using the above code. Use this token to use here map API’s
