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?
seems like expected functionality to me, you're looping over the
contents of the directory and that can only be a file or a directory -
thus SplFileInfo seems correct?
in short you don't call hasChildren() on SplFileInfo, you call it on
RecursiveDirectoryIterator.
From the docs:
RecursiveDirectoryIterator::hasChildren — Returns whether current entry
is a directory and not '.' or '..'
RecursiveDirectoryIterator::getChildren — Returns an iterator for the
current entry if it is a directory
Thus this is how you call getChildren properly:
$dir = new RecursiveDirectoryIterator( dirname(dirname(__FILE__)) );
foreach($dir as $splFileInfo) {
if( $dir->hasChildren() ) {
$childDir = $dir->getChildren();
echo get_class($childDir) . ' ' . $childDir->getPath() . PHP_EOL;
}
}
many regards,
Nathan
