I'm trying to access facebook login without sdk with php that's why I get access_token from facebook like below:

array(1) [""access_token":"xxxxxxxxxxxxxxx","token_type":"bearer","expires_in":543543581"]=> string(0) "" 

but i want only access_token => "xxxxxxxxxxx" like this $access_token['access_token'];

i already try like :

 if(isset($access_token['access_token']) || array_key_exists('access_token', $access_token))

or
parse_str($access_token, $token_array);

but no luck!!

How could I do this?

public function facebookAction()

 if(isset($_REQUEST["error"]))
 
 $this->flashSession->error("ERROR:: ".$_REQUEST['error']);
 return $this->response->redirect('index'); 
 
 elseif(isset($_REQUEST["code"]))
 
 if(isset($_REQUEST["state"]) && $_REQUEST["state"]==$_SESSION["state"])
 
 $access_token = $this->get_access_token();
//[ Problem is here ] 
 $raw = file_get_contents("https://graph.facebook.com/me?fields=id,name,email,picture,gender&access_token=".$access_token);


 $data_array = json_decode($raw,TRUE);
 $fbid = $data_array['id'];
 $fbmail = $data_array['email'];
 $this->session->set('id', '1000');
 $this->session->set("uname", $fbmail);
 $this->flashSession->success("SUCCESS:: You are now flying with Phalcon!");
 return $this->response->redirect('index');
 else $this->flashSession->error("ERROR:: Request STATE & CODE Error!");return $this->response->redirect('index'); 
 else $this->dialog(); 
 

function generate_state() return md5(uniqid(rand(),TRUE)); 

function dialog()
 $app_secret = "bbbbbbbbbbbbbbbb";
 $app_id = "aaaaaaaaaaaaa";
 //$auth_type = 'rerequest';
 $redirect_uri = urlencode("https://localhost/firefly/Oauth/facebook"); 
 $fbPermission = array('email');
 $defaultGraphVersion = 'v3.2';
 $state = $this->generate_state();
 $_SESSION["state"] = $state;
 return $this->response->redirect('https://www.facebook.com/'.$defaultGraphVersion.'/dialog/oauth?client_id='.$app_id.'&scope=email&redirect_uri='.$redirect_uri.'&state='.$state);

function get_access_token()
 $app_secret = "bbbbbbbbbbbbb";
 $app_id = "aaaaaaaaaaaaaa";
 $redirect_uri = urlencode("https://localhost/firefly/Oauth/facebook"); 
 $code = $_REQUEST["code"];
 $response = file_get_contents("https://graph.facebook.com/oauth/access_token?client_id=".$app_id."&redirect_uri=".$redirect_uri."&client_secret=".$app_secret."&code=".$code);
 json_decode($response, $access_token);
 return $access_token;

in get_access_token change parse_str to json_decode;

parse_str('"access_token":"xxxxxxxxxxxxxxx","token_type":"bearer","expires_in":543543581', $res);

print_r($res);

Output

Array
(
 ["access_token":"xxxxxxxxxxxxxxx","token_type":"bearer","expires_in":543543581] => 
)

Sandbox

Parse string just takes the string and treats it like this, similar to if it was part of a URL query string example.com?foo:

parse_str('foo=bar', $res);
print_r($res);

parse_str('foo', $res);
print_r($res);

Output

//parse_str('foo=bar', $res);
Array
(
 [foo] => bar
)
//parse_str('foo', $res);
Array
(
 [foo] => 
)

And just as foo would become the key in [foo => bar] your string become the key up there.

parse_str Parses encoded_string as if it were the query string passed via a URL and sets variables in the current scope (or in the array if result is provided).

Using Json Decode

print_r(json_decode('"access_token":"xxxxxxxxxxxxxxx","token_type":"bearer","expires_in":543543581', true));

Output

Array
(
 [access_token] => xxxxxxxxxxxxxxx
 [token_type] => bearer
 [expires_in] => 543543581
)

So:

 function get_access_token()
 $app_secret = "bbbbbbbbbbbbb";
 $app_id = "aaaaaaaaaaaaaa";
 $redirect_uri = urlencode("https://localhost/firefly/Oauth/facebook"); 
 $code = $_REQUEST["code"];
 $response = file_get_contents("https://graph.facebook.com/oauth/access_token?client_id=".$app_id."&redirect_uri=".$redirect_uri."&client_secret=".$app_secret."&code=".$code);
 $res = json_decode($response, true);

 //return false or the access_token
 return isset($res['access_token']) ? $res['access_token'] : false;
 //OR
 return $res; //return the whole response

 //---------- old code ---------
 //parse_str($response, $access_token);
 //return $access_token;

So you are getting response as array item, where key is your JSON data and empty value?

Your response is ugly, but this is how you would have grabbed your value:

<?php
 $response = [
 '"access_token":"xxxxxxxxxxxxxxx","token_type":"bearer","expires_in":543543581' => '',
 ];

 $response_key = array_keys($response)[0];
 $response_array = json_decode($response_key, true);
 $access_token = $response_array['access_token'];

 echo $access_token;
?>
