$_SERVER['REMOTE_ADDR'] will give the client's IP address. I don't understand the problem. — Robert

Copy of link below. You previously asked this and no one could answer. Perhaps you could clarify exactly what you are looking for and what is going on? stackoverflow.com/questions/4447716/… — Beaker

$_SERVER['REMOTE_ADDR'] will not work on load balanced sites. For that, and other different situations, use this class:

http://brettic.us/code/php-codeigniter-remote-ip-from-load-balancer/

 class RemoteIP { function ip_address() { if ($this->ip_address !== FALSE) { return $this->ip_address; } if ($this->server('HTTP_X_CLIENTIP')) { $this->ip_address = $_SERVER['HTTP_X_CLIENTIP']; } elseif ($this->server('REMOTE_ADDR') AND $this->server('HTTP_CLIENT_IP')) { $this->ip_address = $_SERVER['HTTP_CLIENT_IP']; } elseif ($this->server('REMOTE_ADDR')) { $this->ip_address = $_SERVER['REMOTE_ADDR']; } elseif ($this->server('HTTP_CLIENT_IP')) { $this->ip_address = $_SERVER['HTTP_CLIENT_IP']; } elseif ($this->server('HTTP_X_FORWARDED_FOR')) { $this->ip_address = $_SERVER['HTTP_X_FORWARDED_FOR']; } if ($this->ip_address === FALSE) { $this->ip_address = '0.0.0.0'; return $this->ip_address; } if (strstr($this->ip_address, ',')) { $x = explode(',', $this->ip_address); $this->ip_address = end($x); } if ( ! $this->valid_ip($this->ip_address)) { $this->ip_address = '0.0.0.0'; } return $this->ip_address; } }
