php - How to limit number of logins at a time? -

-

hello have website. created using php,mysql. want set limit like.. 10 user can login website @ same time. how can kind of setting? body knows solution kindly me..

use database table store number of logged in users need come way of imposing time limit on users. suggest field in table notes last activity. when new user attempts login need apply logic (pseudocode):

if(<10users){     login } elseif(any of users have no activity 30 mins){     remove user , login } else {     inform user of no space }

you need update last activity every time logged in user visits new page.
