How are you? Hope you all fine. I'm going to try image upload to my google drive using google drive API every thing is going to good i install composer.json file successfully through composer require google/apiclient:^2.0 and i download the credentials.json successfully but the problem is that when i'm going to Generating Access Token through php google-drive.php then i got the verification code but when i put the code into verification place its give me the error like

Fatal error: Uncaught Error: Undefined constant "STDIN" in C:\xampp\htdocs\imagebob\google-drive.php:41 Stack trace: #0 C:\xampp\htdocs\imagebob\google-drive.php(62): getClient() shuja007/Shujaat#1 C:\xampp\htdocs\imagebob\form.php(1): include('C:\xampp\htdocs...') #2 {main} thrown in C:\xampp\htdocs\imagebob\google-drive.php on line 41

so the above error I resolved when someone told me to define the STDIN in top of the code in google-drive.php class but after when i define the STDIN in my code then I face new issue and I don't know about this error meaning can some one help me in this error the error is

Fatal error: Uncaught InvalidArgumentException: Invalid code in C:\xampp\htdocs\imagebob\vendor\google\apiclient\src\Google\Client.php:176 Stack trace: #0 C:\xampp\htdocs\imagebob\google-drive.php(44): Google_Client->fetchAccessTokenWithAuthCode('') shuja007/Shujaat#1 C:\xampp\htdocs\imagebob\google-drive.php(62): getClient() #2 C:\xampp\htdocs\imagebob\form.php(1): include('C:\xampp\htdocs...') #3 {main} thrown in C:\xampp\htdocs\imagebob\vendor\google\apiclient\src\Google\Client.php on line 176
