Description:
------------
On the socket_create_pair page (English & French page, probably also on other languages), the example 1 seems wrong:

http://fr2.php.net/manual/en/function.socket-create-pair.php

This part:

$uniqid = uniqid('');
if (file_exists("/tmp/$uniqid.sock")) {
   die('Temporary socket already exists.');
}

Should probably not be there: $uniqid is not used, and the socket_pair is not file-based.
