What? A 30cm problem? What does that mean? In plain english, why is this not a bug? You understand this domain very well. I don't. At least tell me why this is not correct. Why should the last example I supplied be considered CORRECT? It does not give expected results, there is no documentation on the class and so any behaviour is valid. Is that why? Richard.

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php As i explained there is no error in PHP. This is actually a 30cm problem. ------------------------------------------------------------------------ [2005-10-11 15:12:57] richard dot quadling at bandvulc dot co dot uk Ok (I didn't understand the answer as I don't know why the caching should have any difference). I think I found my problem. <?php class class_DirectoryWalker extends RecursiveIteratorIterator { function __construct($path) { parent::__construct(new CachingRecursiveIterator(new RecursiveDirectoryIterator($path), CIT_CALL_TOSTRING | CIT_CATCH_GET_CHILD), 1); } function __call($func, $params) { return call_user_func_array(array($this->getSubIterator(), $func), $params); } } $objDIR = new class_DirectoryWalker('C:/test/'); $iTotal = 0; $iRight = 0; $iWrong = 0; foreach($objDIR as $sKey => $objValue) { ++$iTotal; echo $iTotal . ' ' . filetype($sKey) . ' ' . $objValue->getType() . ' ' . $sKey . ' ' . $objValue . "\n"; if (filetype($sKey) != $objValue->getType()) { ++$iWrong; } else { ++$iRight; } } echo "Total : $iTotal\nRight : $iRight\nWrong : $iWrong\n"; ?> The directory test contains 1 file. 1 file dir C:/test/file1.txt Object id #3 Total : 1 Right : 0 Wrong : 1 This implies that the foreach() mechanism returns the current item for a key but the next entry for the value. Which is very much NOT what I would expect. I would expect the key to be the filename (as it is) and the value to be the object representing the filename. The question that comes from this is how do I get the object which is the FIRST file? Richard. ------------------------------------------------------------------------ [2005-10-11 14:53:14] richard dot quadling at bandvulc dot co dot uk What I don't understand is why the state is incorrect only on SOME of the results and not all the results. Or am I doing the whole thing wrong? Is there a better set of user documentation for these classes. I get very confused. I shouldn't. I've been doing this for long enough. But I do. I'm getting old. Nearly 40 you know. So, be nice to the old man. I want to use OOP to get all the files and directories from a start point. I also want to add a filter to only return certain files based upon their extension. I don't know the correct way to combine the different classes. Sorry. ------------------------------------------------------------------------ [2005-10-07 20:17:48] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Since you are using a CachingIterator and access the type through it the result is expected. What happens is that the Caching iterator aggrgates the DirectoryIterator. So when you access a value from a method of the Directory iterator it is executed on the DirectoryIteraotr. But the DirectoryIteraotr has already changed it\'s state. To solve this issue, you would need to cache all the information by deriving the CachingIterator. ------------------------------------------------------------------------ [2005-10-07 14:05:18] richard dot quadling at bandvulc dot co dot uk I altered the code just to show those that are different ... <?php class class_DirectoryWalker extends RecursiveIteratorIterator { function __construct($path) { parent::__construct(new CachingRecursiveIterator(new RecursiveDirectoryIterator($path), CIT_CALL_TOSTRING | CIT_CATCH_GET_CHILD), 1); } function __call($func, $params) { return call_user_func_array(array($this->getSubIterator(), $func), $params); } } $objDIR = new class_DirectoryWalker('M:/Datastore'); foreach($objDIR as $sKey => &$objValue) { if (filetype($sKey) != $objValue->getType()) { echo filetype($sKey) . ' ' . $objValue->getType() . " $sKey\n"; } } ?> and get things like ... dir file M:/Datastore/Bandvulc Department Desktops/Sales/bij1100 file dir M:/Datastore/Bandvulc Department Desktops/Sales/bij1100/win2k_xp/english/hpzvip09.dl_ Here we see a directory (filetype()) which the next line is a file within that directory and that line is being shown as a directory when in fact it is obviously a folder. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
