Description:
------------
The dir class method read works if using it just the way it is stated in the documentation, however, if I re-write it to use TRUE=== it fails. See code example:

Reproduce code:
---------------
Original Code Snippet:

<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
   echo $entry."\n";
}
$d->close();
?> 


MODIFIED:
while (false !== ($entry = $d->read())) {

TO:
while (true === ($entry = $d->read())) {

Expected result:
----------------
Expected the alternative version to return true, but it did not.

Actual result:
--------------
Code returned false.
