Edit report at http://bugs.php.net/bug.php?id=54246&edit=1 ID: 54246 Updated by: scottmac@php.net Reported by: ebert at woltlab dot com Summary: DirectoryIterator object loses information once copied into a variable -Status: Open +Status: Bogus Type: Bug Package: Filesystem function related Operating System: Windows 7 x64 (7601 w/ SP1) PHP Version: 5.2.17 Block user comment: N 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.

While methods like 'isDir()' work fine in first loop, they will always fail within second loop. --- C:\Program Files (x86)\PHP>php.exe -v PHP 5.2.17 (cli) (built: Jan 6 2011 17:37:45) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies --- Verzeichnis von C:\inetpub\wwwroot\di 14.03.2011 13:33 <DIR> . 14.03.2011 13:33 <DIR> .. 14.03.2011 13:41 427 di.php 14.03.2011 13:33 <DIR> directory 14.03.2011 13:33 0 randomFile1.txt 14.03.2011 13:33 7.334 randomFile2.odt 14.03.2011 13:33 0 randomFile3.bmp 4 Datei(en), 7.761 Bytes 3 Verzeichnis(se), 23.774.224.384 Bytes frei 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() .
