You want's login with google funcationality in your app. This is done by Google Contacts API and OAuth authentication. I searched and provide a tutorial for you to consult for this topic - Tutorial: Google Contacts API Version 3.0 & OAuth 2.0

Thank you.

You can do this with Google's OAuth 2.0 API. Daniel11 seems to be going around linking to tutorials on his own website, but in this case, it's not entirely applicable because you're looking for information on doing it in PHP, and Daniel's tutorial implements C#.NET. Additionally, it talks about the Contacts API, which I think is not the one you want. You want the Google Sign-In platform, as so:

https://developers.google.com/identity

https://developers.google.com/identity/protocols/OAuth2
