When you pass a keyed array of sockets into socket_select the keys are lost.

Reproduce code:
$clients = array();
$listener = socket_create_listen(9999);
$clients[uniqid()] = socket_accept($listener);

$read = $clients;
socket_select($read, $w = NULL, $e = NULL, NULL);

Expected result:
to test: 
telnet localhost 9999
enter text, hit enter.

I expect the second print_r($read) to have the same key as the first print_r($read).

Actual result:
     [47bcc1d71874d] => Resource id #5
     [0] => Resource id #5
