I'm trying to use gethostbyaddr, string $ip_address , to get the name of the machine that I point to with $ip_address .
I have been given the case that, on the local machine the /etc/hosts has several names defined for ip loop , such that:
127.0.0.1 localhost test test2 test4
If I execute gesthostbyaddr(127.0.0.1) , it always returns the first element (in this case, localhost ).
How could I get ALL the items, that is, localhost , test , test2 , test4 ?
Is there a function similar to gethostbyaddr that returns an array of the host?
