php - Delete login data from database when timestamp expires MySQL -

i have database:

login_id -> ai, int, pk login_token -> varchar(255) login_userid -> varchar(255) login_expires -> varchar(255) 

login_expires unix timestamp.

the login_token bound cookie. when cookie expires, row database login_token cookie should deleted too.

what's easiest why this?

with mysql >= 5.1 can use event scheduler:

create event expired on schedule @ current_timestamp + interval 5 minutes    delete your_table    login_expires < now();
