... 

I expect it to return "ACK", then return " " because of the '\n' and
break the while loop, which it doesn't. As far as I understand from the
manual it should.

So what's wrong in this? Of course it's 4 chars. 
ACK\n == 4 chars.

Oh and it doesn't break the while-loop.

CODE:

echo "Reading daemon response:\n";
while( $out = socket_read($socket, 2048, PHP_NORMAL_READ) ) {
	//if( strncmp( $out, 'ACK', 3 ) == 0 ) break;	
	var_dump( $out );
}

RESULT:

OK got socket.
Attempting to connect to '127.0.0.1' on port '8001'...OK got
connection.
OK wrote connection string 'REQ
'.
Reading daemon response:
string(4) "ACK
"

Note the trailing '\n' to the ACK response, also note it's a string(4).
