JSON Question

Echo JSON response with PHP

I am trying to echo a portion of my JSON response from the Plaid API.

Here is the code:

$data = array(
"client_id"=>"test_id",
"secret"=>"test_secret",
"public_token"=>"test,fidelity,connected");
$string = http_build_query($data);

//initialize session
$ch=curl_init("https://tartan.plaid.com/exchange_token");

//set options
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//execute session
$exchangeToken = curl_exec($ch);
echo $exchangeToken;
$exchangeT = json_decode($exchangeToken);
echo $exchangeT['access_token'];
//close session
curl_close($ch);


Here is the response:

{ "sandbox": true, "access_token": "test_fidelity" }


I also get a 500 Internal Server Error, which results from the echo $exchangeT line. I want to take the access_token portion of the JSON response, echo it to verify, and eventually save it to a database.

Answer

If you pass true as second parameter in your json_decode then you will get an array instead of object so change this

     $exchangeT = json_decode($exchangeToken, true);
// it wii output as $exchangeT = array('sandbox'=>true,'access_token'=>'test_fidelity');
        echo $exchangeT['access_token'];
