Simplified fake IP swipe ticket implementation in PHP

Simple fake IP swipe ticket implementation in PHP

In general, our code to obtain the user's real IP is roughly the same ...

/** * Get the IP address of the remote visitor * * @return string */function real_ip_addr () {static $remote _ip_address = Null;if (! $remote _ip_address) {$vars = Array (val ($_server, ' Http_client_ip '), Val ($_server, ' http_x_forwarded_for '), Val ($_server, ' remote_addr '),) ; foreach ($vars as $var) {if (!empty ($var)) {$remote _ip_address = $var;} Continue;} if (Empty ($remote _ip_address)) $remote _ip_address = ' Unknown ';} return $remote _ip_address;}

?

Typically 3 environment variables are used to refer to "client" IP: $_server[' http_client_ip ' and $_server[' x_forwarded_for '] and $_server[' REMOTE_ADDR ') in fact, These 3 environment variables have limitations. The first two are free to forge. As long as you set the corresponding value in the HTTP header, any character can be, and the 3rd environment variable, if the user uses an anonymous proxy, then this variable shows proxy IP
