RE: [PHP] IP Address Converted to Computer Name

Thanks for your response David. I am new to PHP. Are you saying that the code would look like this: <? gethostname for $IPADDR; if $HOSTNAME = $IPADDR print "$HOSTNAME" ?> Would I then put the $HOSTNAME into my mail() script. Sorry for the trouble.

That said, there may be a flaw in your logic in the code snippet above :-) What you are saying is: gethostname for IPADDR; if HOSTNAME = IPADDR print HOSTNAME which will only work if the resolved hostname is the same as the IP address; I suspect that is not what you want? -- David Robley Techno-JoaT, Web Maintainer, Mail List Admin, etc CENTRE FOR INJURY STUDIES Flinders University, SOUTH AUSTRALIA Bald: follicularly challenged. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
