I have discovered that when I foreach over a RecursiveDirectoryIterator

I would expect it to be a RecursiveDirectoryIterator. How do I do a
hasChildren() on SplFileInfo?
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?
@ Marcus, what was the reasoning not to fix this? And why did it break
in 5.2.6?
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();
}
