PHP Fatal Error & GitHub Incomplete Download
Hi Experts,
I had this question after viewing How Do I "Install the Google Client Library".
I guess I closed the above too early, but after downloading from https://github.com/google/google-api-php-client by clicking Clone or Download, then Extracting the .zip, I noticed that all files and folders don't get downloaded (I tried twice), such as examples/, styles/, tests/, and most files under the root directory when compared to the following screenshot of what is actually downloaded.
Why aren't all files and folders getting downloaded?
Secondly, and most importantly, after extracting the download into my project director, and running the following code,

If you refer to my original post, you will see that I'm on a Windows environment and never needed to use GitHub, but I didn't have a chance to test the above until now.
Thank you.

I posted an update to your other question. Start over, and install via using composer.
Start at the console if you have not already. Add your project there, then download the sdk via composer. The instructions are https://developers.google.com/api-client-library/php/start/get_started. There are also some code examples.
On github, there are also instructions there as well for installing via composer. https://github.com/google/google-api-php-client#download-the-release
When everything gets downloaded using composer, composer will take care of auto loading all the other files required with the autoload.
Once you have all of this installed. Just remember making an api call is a two step process. First you are submitting your own credentials to get a token which gets returned in the first call. Then submit the token with each subsequent api call.

Thanks Scott, I have gone through https://developers.google.com/api-client-library/php/start/get_started, which is a good refresher, but is only theory and does not pprovide detailed instructions.
I think you are saying that I need to install the Composer, then install the SDK through the composer.
Based on that, what is the Composer, is that Google, what does it do, and where do I get it?
What is
Remember, I'm not familiar with MAC, Linux and GitHub - do I need to be?

With a little research, I found that Composer is a dependency manager, that takes care of updates. Plus, composer needs to be installed on the server, but this particular application is going on a shared hosting. What if they don't have Composer?
Can I not use the Google Calendar SDK (or, just API) without using Composer?
I understand that using Composer might be preferred and a personal preference, but can I not just download the files and just use them, similar to PHPMailer or TCPDF?

You're correct in your assumption that Composer is a dependency manager. The download you've grabbed is just the src folder and doesn't include the dependencies which is why they suggest installing it via Composer. That's part of the beauty of Composer - devs don't need to ship the project dependencies - just a composer.json file.
Generally with raw source code like this, the idea is that you clone the repo and then run Composer - you then have the full stack set up and ready to go.
As for running it on a server, you could if you wanted to, just install it locally using Composer - that would pull all the relevant deps into your local environment, and you could then develop and test locally. Once your dev is done, you could upload all relevant files to the Server manually.
Alternatively, there is a Releases page available for the API which includes all the relevant dependencies, so it may be better for you to just download a Release that's already packaged - heres the page you need -> https://github.com/google/

I downloaded the packaged release, and received the following error
I, then deleted all API folders from my project, installed Composer, then installed the Google API through the Composer, and I got the same error.

OK - the error should be fairly self-explanatory. You're trying to call your page in a web browser when you should be calling it from the command line (CLI). If you have PHP setup correctly on your windows machine, then from the CLI you need to type the following:
php index.php
php index.php
From the command line, when I run it it is asking me for verification code? Where do I get that?
As well, why is it only working on the command line, when it is a web application?

OK. Reading through your code, it looks like it should ask you to visit a URL ("Open the following link in your browser"). When you open that link, it will ask you to log in to Google and Authorise your application (using oAuth). Once you've done that it will redirect back to whatever URL you setup as the callback when you created the API Credentials in your Google API Console. That URL will include a querystring that contains the verification code (yourCallback.php?code=xxx
The reason it's only working on the command line is because that's what your code tells it to do!!

Copying that oAth in my command line worked, but:
1- When I comment out throw new exception...and run it in my browser I get
PHP Notice: Use of undefined constant STDIN - assumed 'STDIN' in C:\inetpub\wwwroot\test\gm

Why is this, and why is it a part of the original sample code provided at
https://developers.google.com/google-apps/calendar/quickstart/php
I mean...it should be intended to be a web application, so why it is looking for the command line by default, should it not be a quick start sample to get you going?

It clearly says that you will have a simple PHP command-line application!
If you want to develop a web-app then you're going to need to code it very differently. I would start by referring to the API Client docs - https://developers.google.
