RecursiveDirectoryIterator and foreach

[rpanning]

I have discovered that when I foreach over a RecursiveDirectoryIterator (see example below) the $item actually turns into a SplFileInfo object. I would expect it to be a RecursiveDirectoryIterator.

However, if I change it to a non-recursive, DirectoryIterator, $item is what I would expect, DirectoryIterator. I've tested this with 5.2.8 and 5.3b1. I'm guessing this is an issue with my setup as I'm sure I've gotten this to work before...

$dir = new RecursiveDirectoryIterator('/path/to/dir');
foreach ($dir as $item) {
print get_class($item) . "\r\n";
}

Alright, I've found a related PHP bug report. http://bugs.php.net/bug.php?id=44018

It seems that the default behavior is to return a SplFileInfo object. However, if 0 is passed as a flag then a RecursiveDirectoryIterator should be returned. However, I cannot seem to get that to work with 5.2.8. Testing previous versions, this option no longer works as of 5.2.6, but did in 5.2.5.

This seems like a bug to me, however that bug was marked as "Wont Fix". The default behavior should be RecursiveDirectoryIterator as there is a flag for CURRENT_AS_FILEINFO. Any thoughts on that?

In relation, I've found a workaround, use while(). That way I'm always working off of the $dir. I'd rather use foreach though..

$dir = new RecursiveDirectoryIterator('/path/to/dir');
while ($dir->valid()) {
print get_class($dir) . "\r\n";
$dir->next();
}
