Description:
------------
When you pass a keyed array of streams into stream_select the keys are lost.

The behaviour I am seeing is similar to the socket_select bug 44197.

Test script:
---------------
<?php
$read["myindex"] = $mystream;
$write = NULL;
$except = NULL;

var_dump($read);

stream_select($read, $write, $except, 0);

var_dump($read);

?> 


Expected result:
----------------
Assuming $mystream changes status and there is data available for reading...

array(1) {
  ["myindex"]=>
  resource(11) of type (stream)
}
array(1) {
  ["myindex"]=>
  resource(11) of type (stream)
}

Actual result:
--------------
array(1) {
  ["myindex"]=>
  resource(11) of type (stream)
}
array(1) {
  [0]=>
  resource(11) of type (stream)
}
