stream_socket_client and /etc/hosts file

Does stream_socket_client use the /etc/hosts file? I'm using Mac OSX
10.5.3 as a development platform and VMware Fusion for VM hosting. I
have a OpenSUSE Linux VM that has an Apache 2 web server with multiple
named virtual hosts. I use the Macs /etc/hosts file to provide DNS
resolution for the development web sites. I can ping the DNS names and
browse to them with no issues. For example:

ping dev.example.com

Works no problem (resolves to 172.16.182.128 - the IP VMware assigns
to the Linux VM)

Firefox & Safari can browse to dev.example.com no problem

However if I use stream_socket_client with a URI of tcp://dev.example.com:80
it fails.

Any ideas?

use /etc/hosts. That is strictly part of TCP/IP's address resolution
protocol (ARP) handling.

Without the error, I have no idea what might be wrong.

conversion is Layer 3 (network).

But each method described should yield the same result since the TCP/
IP stack entry point is more or less the same and above the resolver
(whose job it is to turn IP names into addresses).

An error message would be helpful. Or try capturing the network
packets.

But either way - it's TCP/IP which handles it.

The call is reporting the following:

Error # : -1081773134
Error String : ""

I'm calling the function with a timeout of 15 and the
STREAM_CLIENT_CONNECT flag.

Thanks for the comments so far. (I was going to comment on the ARP
resolution and DNS stuff but someone beat me to it. And just to add to
that conversation DNS would be more of an application layer protocol
since it is more like to SMTP than an actual network protocol - like
ARP, ICMP, TCP, UDP, etc... Basically DNS isn't needed to make the
network work and is really only required by humans and other higher
level protocols. I've designed enterprise networks and security for
years now - taking time off of programming and now back to programming
- so I've got what isn't working, just not sure from a PHP level why?)

What's the actual code you're using?
