Azure AD SSO with PHP

Hi,

I am using Code Igniter as my coding language for my CRM application and want to integrate Azure AD SSO for login screen. I tried to lookup some documents or links online for the same but couldn't find anything related to PHP. I found a code and it was for Node.js and it is working without any problems, since my CRM Login creates a session cookie and if I integrate NodeJS, it will also create a session cookie. So, I don't want to manage 2 cookies for the same user at the same time.

It would be great, if someone can help me out in the same.

Thanks in advance.
