Description:
------------
Standard latest xampp setup (including PHP 5.0.4).
When using socket_create_listen(port), it does not listen on all interfaces as the docs indicate that it would. I was unable to connect to the machine using anything other than localhost (127.0.0.1). 

The workaround is to use socket_create, socket_bind (with 0.0.0.0 as the address) and socket_listen to accomplish the same task.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

I have the same problem with PHP 5.1.4 version. The soket can't receive connections from internet, but can do it in local network. But when i put 0.0.0.0 in address socket_bind I begin to receive connections.

In some (many) connections i receive warning in socket_write and socket_read because "unable to write/read from socket [0]". 

My operating system is: Windows XP.

Same issue.  Small test script:

===================================================
<?php

$server = socket_create_listen(5900);
if (!$server){
	throw new Exception('Cannot create socket');
}

$client = socket_accept($server);
if (!$client){
	throw new Exception('Client connect failed.');
}

while ($client){
	$data = socket_read($client, 1024);
	if ($data != ""){
		$data = trim($data);

		socket_write($client, 'You said: '.$data."\r\n");
		if ($data=='bye'){
			socket_close($client);
			socket_close($server);
			$client=null;
		}
	}
	else {
		socket_close($client);
		socket_close($server);
		$client=null;
	}
}
