Description:
------------
I use php://memory to save resources when unit testing, I found it possible to write to the stream despite opening it read only. Not sure if this is the desired behaviour.



Reproduce code:
---------------
<?php
/**
 * php://memory bug 
 */

$fh = fopen('php://memory', 'r');
var_dump(fwrite($fh, 'dave'));

?>


Expected result:
----------------
int(0)

Actual result:
--------------
int(4)
