Pinging specified port in PHP on *nix

[sneeze]

Hi.
Anyone knows how to ping a specified port with nix using
PHP?
The purpose is to display info on my site on what inet-apps im
using at the time a visitor is surfing my website.
Im using exec("ping my.ip.number.here -c 1").
Since nix cant handle ip:port usage, i was wondering if there
is another way to do this.

Hmm... excuse me if this makes you all confused..

To clear out suspicious thoughts about the porpose of this script, i would LOVE any suggestions other than 'ping' to solve this problem.

ping is not used to check just a port, it's used to check if a computer is online...

Are you trying to see if a port is open? If you are, then use fsockopen() to connect to that port. If the function returns a valid socket handle, then the port is open. If it returns false, then the port is not open.

If you are on nix just download and install nmap, which might already be installed. Then call it through exec(), it usage is nmap ipaddress. That will show you what ports are open on that ip.

Thanks alot, dudes..
If i get a working script together, ill upload it to phpbuilder.
Seems like a good idea if anyone wants live statistics about
themselves through their website.
