如何限制家庭用户访问php网站?

i have a php application for a company, using MySql Database, what i want is there any way to restrict the users to access to their accounts from home? since we are not using a static IP's

There are several approaches:

  • Host the site on a company LAN so it isn't accessible over the Internet
  • Get a static IP address (you're a company, you should be able to get an Internet connection which comes with static IPs, my consumer ADSL package comes with one!).
  • Perform authentication with client side SSL certificates and install them on the browsers of the office computers
