Dicovering the user's IP.

[furma]

How do I know what the user's IP, who's visiting my website right now, is?

I need it in a variable in order to present it to the uesr himself.

Hi Furma

Try this link to the manual page.

This will give you the IP address being used by the client. Whether it is the real IP address of the remote machine is a whole other issue.

Not sure why you would want to present the user his/her own IP, but I'll leave that up to you.

or the website is down..

The link is fine - I just tried it myself. It would be highly unusual for the PHP website to actually be 'down', but if it was then it certainly isn't now.

$_server['remote_addr']

$_SERVER['REMOTE_ADDR'] (case sensitive) gives you the address of the client. This is not the IP address of the user; users don't have IP addresses.

The IP address may belong to the user's machine, or a shared machine (in the case of a multiuser environment), a proxy, a NAT firewall, or something else.
