For at least some months, gethostbyname() in sockets.c has
been replaced by gethostbyname() in ext/standard/dns.c
which does

memcpy(&in.s_addr, *(hp->h_addr_list), sizeof(in.s_addr));

Could you try the latest CVS? Could you test both
gethostbyname() and gethostbynamel() in PHP? They do it
differently. I think both should work.

I though about this too at first, but the right information is in both cases stored in 
the host_struct->h_addr_list.
But the information is only correct if you memcpy it to a.s_addr, instead of 
typecasting it.

It sounds like a DNS problem to me. It would be wise if you check that out too.

Works for me just fine with latest CVS. Please try the 
latest CVS snapshot from

The gethostbyname doesn't seem to work on some of the systems I use. The problem only 
occurs on some machines, others work fine. The problem only occurs on 4.0x, but not on 
3.0x on the same machine.
All machines use the same build of php4.

For example:
   echo (gethostbyname (""));


The bug? also affects functions like mysql_connect.
I am unable to connect to a sql server unless I replace the hostname with an ip 

I've traced the problem back to sockets.c, line 817:
a.s_addr = (int) (*(host_struct->h_addr_list[0]));

If I replace the code above with the equivalent code used in php3 the problem is 
memcpy (&a.s_addr, *(host_struct->h_addr_list), sizeof (a.s_addr));

If you need more information please let me know.
