Re: getting the IP address off a visitor

Here is a function a found on php.net that turns the IP. Everything that Justin said is true too. If they have a dial-up user or are behind a proxy server you can't track them. Also if you are saving this to a database table it will get very big fast, just like Justin said. I would create a table just for today's hits, then have a script run at 12:01 everyday that creates a summary record and saves it to another table. Then delete the records from the today hits. You could setup a crontab to run the script for you. function getip() { if (isSet($_SERVER)) { if (isSet($_SERVER["HTTP_X_FORWARDED_FOR"])) { $realip = $_SERVER["HTTP_X_FORWARDED_FOR"]; } elseif (isSet($_SERVER["HTTP_CLIENT_IP"])) { $realip = $_SERVER["HTTP_CLIENT_IP"]; } else { $realip = $_SERVER["REMOTE_ADDR"]; } } else { if ( getenv( 'HTTP_X_FORWARDED_FOR' ) ) { $realip = getenv( 'HTTP_X_FORWARDED_FOR' ); } elseif ( getenv( 'HTTP_CLIENT_IP' ) ) { $realip = getenv( 'HTTP_CLIENT_IP' ); } else { $realip = getenv( 'REMOTE_ADDR' ); } } return $realip; } _________________________________________ Mark McCulligh, Application Developer / Analyst Sykes Canada Corporation www.SykesCanada.com (888)225-6824 ex. 3262 mmcculli@SykesCanada.com ----- Original Message ----- From: "Sebastian Marcu" <sebimarcu@yahoo.com> Newsgroups: php.general To: <php-general@lists.php.net> Sent: Thursday, July 04, 2002 12:00 PM Subject: getting the IP address off a visitor > Hi there, > > I am new to PHP and need some help. > I was wondering if there is a way to get hold of the IP address of a site > visitor with PHP.
