使用FB和Google API与PHP时出错

Question

I am using FB SDK and Google API for login on my website. If I comment one API then other API works perfectly.

require_once '../vendor/autoload.php';

require_once '../src/fb.php';

require_once '../src/google.php';

if(isset($_SESSION['checkLogin'])){
        echo "<a href='logout.php'>Logout</a>";

    }

If I run simultaneously then got error If I run Google then got this error

Facebook SDK returned an error: Cross-site request forgery validation failed. Required GET param "state" missing.

If I run FB then got this error

Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: `POST https://www.googleapis.com/oauth2/v4/token` resulted in a `400 Bad Request` response: { "error": "invalid_grant", "error_description": "Malformed code." }

Can someone help me with this??
