 Status:           Bogus

 Operating System: Linux (fedora core 6  i think)

Hi Colder,

I did consider cloning the object, but the behaviour is still wrong
(imo):-

// $files[] = $file; change to -> 
$files[] = clone $file;


Actual result:
--------------
test.php / 18 bytes
. / 4096 bytes
.. / 4096 bytes

Second loop:-
test.php / 18 bytes
test.php / 18 bytes
test.php / 18 bytes


Also, I disagree that original report expected behaviour (from a PHP
User's perspective), even if it makes sense from an SPL perspective.

DirectoryIterator::current() returning _itself_ seems pretty crazy to
me? Why doesn't it return an SplFileInfo object, representing the file
in question?

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Even if it's odd, this is actually expected,
DirectoryIterator::current() returns itself, so you're storing the same
iterator multiple times in your array, consider either using clone or
fetching directly the informations in your foreach.

Description:
------------
When looping over a $directorIterator using FOREACH something goes
wrong when assigning the "as" variable to an array.




Reproduce code:
---------------
$filePath   = 'PUT YOUR TEST PATH HERE';
$dir        = new DirectoryIterator($filePath);
$files      = array();

foreach ($dir as $file){
    $files[] = $file;
    echo $file-> getFilename(), " / ", $file->getSize(), " bytes\n";
}

echo "\nSecond loop:-\n";

foreach ($files as $file2){
    echo $file2-> getFilename(), " / ", $file2->getSize(), " bytes\n";
}


Expected result:
----------------
(Depends on the files but assuming a single file in the directory)

test.php / 18 bytes
. / 4096 bytes
.. / 4096 bytes

Second run:-
test.php / 18 bytes
. / 4096 bytes
.. / 4096 bytes

Actual result:
--------------
test.php / 18 bytes
. / 4096 bytes
.. / 4096 bytes

Second run:-
 / 4096 bytes
 / 4096 bytes
 / 4096 bytes
