登录系统在数据库中存储会话

Question

What am I making?

I am developing a login system for my own website, when people login a session_token is generated, and saved using PHP sessions. The generated session_token will also be inserted to a database table, along with the logged in user's id, and session_expire datetime.

Every time the user returns to my website, it checks if the session_token exists and has not expired, in the sessions database table.

Question

How can I prevent my sessions table from getting full of expired session_tokens? I don't want to run a cron_job to remove expired sessions every x minutes.

在不使用cron作业的情况下，您可以使用MySQL Event Scheduler ，或者当您检查令牌是否已过期时，可以将其删除（如果令牌已过期）。
