Summary: DirectoryIterator object loses information once
copied into a variable
-Status: Open

Package: Filesystem function related
Operating System: Windows 7 x64 (7601 w/ SP1)
PHP Version: 5.2.17

Private report: N
New Comment:
It's a reference to a single object and as it goes through the loop it's
actually
off the end making it empty.
If you want a copy use clone.

Description:
------------
Storing all DirectoryIterator objects fetched previously with an
instance of DirectoryIterator within an array seems to make stored
objects to lose all data.
While methods like 'isDir()' work fine in first loop, they will always
fail within second loop.

Test script:
---------------
<?php
$array = array();
$dir = 'C:/inetpub/wwwroot/di/';
$it = new DirectoryIterator($dir);
foreach ($it as $obj) {
if ($obj->isDot()) continue;
var_dump($obj);
if ($obj->isDir()) echo $obj->getFilename() . ' is a directory.<br
/>';
else echo $obj->getFilename() . ' is a file<br />';
$array[] = $obj;
}
echo '<hr />';
foreach ($array as $obj) {
var_dump($obj);
if ($obj->isDir()) echo $obj->getFilename() . ' is a directory.<br
/>';
else echo $obj->getFilename() . ' is a file<br />';
}
?>
Actual result:
--------------
object(DirectoryIterator)#1 (0) { } di.php is a file
object(DirectoryIterator)#1 (0) { } directory is a directory.
object(DirectoryIterator)#1 (0) { } randomFile1.txt is a file
object(DirectoryIterator)#1 (0) { } randomFile2.odt is a file
object(DirectoryIterator)#1 (0) { } randomFile3.bmp is a file
(<hr />)
object(DirectoryIterator)#1 (0) { } is a directory.
object(DirectoryIterator)#1 (0) { } is a directory.
object(DirectoryIterator)#1 (0) { } is a directory.
object(DirectoryIterator)#1 (0) { } is a directory.
object(DirectoryIterator)#1 (0) { } is a directory.
