facts; shared server, php 5.6, linux not windows. apache.

trying achieve; google login plus google analytics data retrieval; without using composer

hurdle; gooogle docs tutorial doesnt work!

rant; stackoverflow's 2 link policy stupid. driving me crazy. had google login on previous site, easy. come again new site , it's changed. firstly, no options install components log in google, have upload 5000 src files 99% wont used! follow ( https:// developers.google.com/analytics/devguides/reporting/core/v3/quickstart/web-php ) google's exact instrutions tee , error.

"fatal error: class 'google_client' not found in..."
