OAuth 2.0 Client VS msgraph-sdk-php

League/oauth2-client has a lot of implementations

Have a look on this one https://oauth2-client.thephpleague.com/

In regards to oauth the phpleague packages are fairly popular. Again, the flow requires some redirect dancing so not something that can be (simply) just a single boolean-returning method on the PHP side. Additionally, oauth is a relatively weak standard (Especially where you want to verify identity) in which case platform specific actions/tweaks are needed hence why most use platform-specific oauth libraries. OIDC builds upon oauth to standardize the flow, including getting the identity, but it isn't supported by all platforms offering oauth.

For the client side, I'll be using the library league/oauth2-client.

"Login with Google/Facebook/Twitter/etc": That's called OAuth2 and quite easy to implement. This package is good OAuth2 client to start.

I'd recommend using a library - for Azure AD OAuth we've been using https://github.com/thephpleague/oauth2-client + https://github.com/thenetworg/oauth2-azure (see also https://oauth2-client.thephpleague.com/providers/thirdparty/ )

For Azure AD, I'd recommend the combination of https://github.com/thephpleague/oauth2-client for the authentication part (getting the token) and the Microsoft Graph SDK for then using the token to get information about the user https://github.com/microsoftgraph/msgraph-sdk-php

Here's a good example of that: https://github.com/thephpleague/oauth2-client/blob/master/.gitattributes

looks like there is an SDK, which is usually the preferred route https://github.com/microsoftgraph/msgraph-sdk-php

The official Microsoft Graph PHP SDK works just fine for us. I don't see much use for a Symfony specific library, to be honest, since mapping the Graph query results to database entities will likely be individual for each project.

Regarding basic auth - you're covered there, SMTP is the sole protocol where Basic Authentication will continue to work with no planned end date. However, there is a Graph SDK for PHP in case you want to check out doing things the 'modern' way - https://github.com/microsoftgraph/msgraph-sdk-php - I should note I have no experience with it.

Try to use this library: https://github.com/microsoftgraph/msgraph-sdk-php

For Azure AD, I'd recommend the combination of https://github.com/thephpleague/oauth2-client for the authentication part (getting the token) and the Microsoft Graph SDK for then using the token to get information about the user https://github.com/microsoftgraph/msgraph-sdk-php

This is my first time using the Microsoft Graph SDK for PHP and I'm trying to programmatically create and assign tasks to users in my directory (Generally what's described here). I might just be getting overwhelmed reading through all the documentation so quickly but I feel like I am missing or misunderstanding something.
