Re: [PHP] How to resolve IP with PHP

2002-01-21 Thread gaouzief 

hi,

i think there is a function that does just that
look for gethostbyaddr($ip) in the documentation
beware of the implication on the ressources , this function performs a reverse dns 
lookup which can be time consuming

regards

do something more complicated?

thanks so much!

Did you look at the function list to see if gethostbyname() or something
similar exists?
