Join David Powers for an in-depth discussion in this video Logging out, part of PHP: Managing Persistent Sessions.
- The autologin class…preserves session data on every browser or computer…where the user selects the Remember me option.…So it's important to give users the option…to be forgotten, as well.…That's the role of the classes of the logout method.…The definition begins on line 168…and it has a single parameter, all,…which is set by default true, making it optional.…If all is true, the logout method calls the deleteAll method…which was described in the previous video.…
This deletes all records of the autologin table…associated with the current user key.…In other words, it prevents the user…from being automatically logged in on any computer…without going through the normal authentication process…and selecting Remember me again.…If all is false, the else block calls the parseCookie method…to get the single use token from the autologin cookie.…Remember that the token stored as a cookie…is automatically updated…as soon as the user has been authenticated.…
So, the token that's returned this time…is intended for the user's next visit…
