can i get the visitors ip with php?

[Anon]

for a tracker i need the visitors ip. last time i coded it with javascript, which calls an image with ip as a parameter.

but it would be much more cleaner, if the ip would be logged right when the script is called.

Use getenv(REMOTE_ADDR)

I almost forgot one thing. If user is in the ISP Cache server, the HTTP_X_FORWARDED_FOR is also set.

if (getenv(HTTP_X_FORWARDED_FOR)){
$ip=getenv(HTTP_X_FORWARDED_FOR);
}
else {
$ip=getenv(REMOTE_ADDR);
}
