Am trying to parse a response i get from GoogleFit API. Here is the snippet i wrote:

1 $result = curl_exec($ch);//execute post
2 curl_close($ch);//close connection 
3 $newResult = json_encode($result); 
4 Log::info($newResult); 
5 return $newResult;

And the response looks like this:

{ "access_token": "ya29.Il-4B1111", "token_type": "Bearer", "expires_in": 3600, "refresh_token": "1//09uJO5Lo7CFhyCg3333", "scope": "" } true

Line 4 is Logging instead of the response.


I want to store access_token, refresh_token, and expires_in in my db. I cant access the properties of the response either. Please help

You can decode/parse the JSON response in the following ways:

  1. object
  2. PHP associative array

for the second option, use true in json_decode()

i.e. you can use following:

const NL = PHP_EOL;

$json = '{
    "access_token": "ya29.Il-4B1111",
    "token_type": "Bearer",
    "expires_in": 3600,
    "refresh_token": "1//09uJO5Lo7CFhyCg3333",
    "scope": ""

// object
$jsonObj = json_decode($json);
echo $jsonObj->access_token;
echo NL;
echo $jsonObj->refresh_token;
echo NL;
echo $jsonObj->expires_in;
echo NL;

// associative array
$jsonArr = json_decode($json, true);
echo $jsonArr['access_token'];
echo NL;
echo $jsonArr['refresh_token'];
echo NL;
echo $jsonArr['expires_in'];
