Blocking a website from multiple users is the same as allowing only specific users, one at a time. One way to do this would be to build your site on a webserver that requires access checks. If you want to validate only one user at a time, then a general method might be to create a file that shows whether a user is logged in or not. A very simple PHP script could do this easily. The database file that contains the current status of the website, i.e. either there is someone visiting the site or there is no one visiting the site, is a simple boolean value. It would be set to 1 (one) if there is a visitor viewing the site or 0 (zero) if no one is currently viewing the site. The php entry script can check this file to see if it is zero or one and depending on the status, allow entry to the site (setting the status file so no others will be allowed entry) or deny entry. There are some more interesting questions implied here. For example, how would you confirm status? Also, what webserver are you using? If you are using Apache, I think an .htaccess might have the capability to do all of this for you but I am not an Apache expert. Maybe there is one out there that can answer this. I hope this gives you an idea or two.
