PHP - Verify user token on every request

Question

Here is a scenario: Whenever a user logs in, I send the user token along with the response and save it in localStorage. Now, I want to make another request and I also want to send the token back for confirmation as a valid token.

Here is a sample MySQL query:

SELECT * FROM news WHERE status = '1'

Currently, I am not checking the token. How will I do that?

Note: The token is in the user table.
