Allow host IP using PHP

Question

How can I resolve the hostname IP address using PHP?

Answer 1

You can use the gethostbyaddr () function.

$hostname = gethostbyaddr($ipAddress); 

Answer 2

Use gethostbyaddr ()

 $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']); echo $hostname; 

You may find that this function may freeze for some time when the address is not found - if this becomes a performance issue for you, check out this comment on the manual , which details the manual method that supports timeout.

Answer 3

gethostbyaddr ()

Answer 4

You must give gethostbyaddr () a shot.
