Connecting to GA4 google analytics data api and google client without composer using php

Hi i am trying to connect to google api so i can get my stats via the browser. I dont want to use composer. How can i do this?

Here is what i have so far.

i downloaded and installed the following dependents
needed libs
Only 1 file included for the grpc library

https://github.com/protocolbuffers/protobuf
https://github.com/googleapis/php-analytics-data
https://github.com/googleapis/gax-php
https://github.com/googleapis/google-auth-library-php
https://github.com/grpc/grpc

I have replaced this code for current code, i want to start over from scratch and go one step at a time. First i will get the dependencies loaded and then i will do the client credentials, and then ill get the property data.

So lets get the dependencies first.

//init arrays
$library_array = [];

//and then we write a cURL or other class to connect because we cant use

 echo "<pre>";
 echo "All dependents loaded and now write a connect process";
 exit;

So how do i verify credentials and connect for google api data now that i cant use the google class BetaAnalyticsDataClient as it requires guzzle which i dont want to use?

Any suggestions would be great thanks 🙂

=========== new code for connection =============

My strong advice here is to watch Linda’s Video here, then you will understand how to use googles oauth2 for authorization and more.
