Description:

Hi!

I try this code but it's a strange result.
I don't receive same result for '.' directory.

Here is my directories structure :
# ll -R tmptest/
tmptest/:
total 12
-rw-r--r--  1 apache apache   21 avr  6 15:56 tmpfile.txt
lrwxrwxrwx  1 apache apache   11 avr  6 15:56 
tmplink.lnk -> tmpfile.txt
drwxr-xr-x  3 apache apache 4096 avr  6 15:56 tmpsubtest
drwxr-xr-x  2 apache apache 4096 avr  6 15:56 tmpsubtest2

tmptest/tmpsubtest:
total 4
drwxr-xr-x  2 apache apache 4096 avr  6 15:56 
tmpsubsubtest

tmptest/tmpsubtest/tmpsubsubtest:
total 4
-rw-r--r--  1 apache apache 21 avr  6 15:56 tmpfile.txt

tmptest/tmpsubtest2:
total 0


Reproduce code:
---------------
<?php
$rdi = new RecursiveDirectoryIterator('tmptest');
// -------- HERE CUT and PASTE X5 code bellow -------
echo '#############################<br />';
echo '__toString is = ['.$rdi.']<br />';
echo 'Current is = ['.$rdi->current().']<br />';
echo 'Key is = ['.$rdi->key().']<br />';
echo 'Valid is = ['.$rdi->valid().']<br />';
echo 'hasChildren is = ['.$rdi->hasChildren().']<br />';
$rdi->next();
// -------- HERE CUT and PASTE END -------
$rdi->rewind();
foreach ($rdi as $content) {
    echo '++++++++++++++++++++++++++++++<br />';
    echo '__toString is = ['.$rdi.']<br />';
    echo 'Current is = ['.$rdi->current().']<br />';
    echo 'Key is = ['.$rdi->key().']<br />';
    echo 'Valid is = ['.$rdi->valid().']<br />';
    echo 'hasChildren is = ['.    $rdi->hasChildren().']<br />';
}
?>


Expected result:
----------------
#############################
__toString is = [tmpsubtest2]
Current is = [tmptest/tmpsubtest2]
Key is = [tmptest/tmpsubtest2]
Valid is = [1]
hasChildren is = [1]

__toString is = [tmpsubtest2]

++++++++++++++++++++++++++++++
__toString is = [tmplink.lnk]
Current is = [tmptest/tmplink.lnk]
Key is = [tmptest/tmplink.lnk]
Valid is = [1]
hasChildren is = []


Actual result:
--------------
In my result, these lines are add in first place.
I don't find '..' directory, only '.' and method 
RecursiveDirectoryIterator::isDot() == True.
