In PHP, you can refresh a JSON Web Token (JWT) using the following steps:<\/p>\n

    \n
  1. Verify if the current JWT is valid, meaning if it has expired or is invalid.<\/li>\n
  2. Extract the payload part of the JWT, which contains the user information and other data stored in the JWT.<\/li>\n
  3. Create a new JWT by adding the previously extracted payload section to it.<\/li>\n
  4. Sign the new JWT with the same key and algorithm.<\/li>\n
  5. Return the newly generated JWT as the refreshed token.<\/li>\n<\/ol>\n

    Here is a simple example code to implement a method for refreshing JWT.<\/p>\n
