Description
A session token is a long, random string. It is used in a cookie to link that cookie to an expiration time and to ensure the cookie becomes invalidated when the user logs out.
This function generates a token and stores it with the associated expiration time (and potentially other session information via the ‘attach_session_information’ filter).
Parameters
- $expiration
-
(int) (Required) Session expiration timestamp.
Return
(string) Session token.
