How to get somebody IP and Port?

Hey guys, I am wondering how do you get the IP and Port of somebody eles computer?

Set up a site and use simple PHP code to log their IP.

And by port, what port do you want? All HTTP traffic goes through port 80.

There are 655*5 TCP ports. Computers can communicate on any one of those, but they don't have any 'assigned' to them like they do with IP addresses.

As for obtaining IP addresses, this has been asked literally every week on this forum; sometimes even more often. Read all these Wiki articles thoroughly, then search the forum:
