This bug has been fixed in CVS.

will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.
Most SPL iterators have a method getInnerIterator() now.

property $it is only in the examples since there is no other way to
implement that in userspace. Anyway i'll add something like that.

This also applies to RecursiveIteratorIterator.

Description:
------------
You cannot access, $it, the iterator passed into
FilterIterator in a child class.
Reproduce code:
---------------
class DirectoryFilterDots extends FilterIterator implements
RecursiveIterator
{
function __construct($path) {
parent::__construct(new DirectoryIterator($path));
}
function accept() {
return !$this->it->isDot();
}
function hasChildren() {
return $this->it->hasChildren();
}
function getChildren() {
return new DirectoryFilterDots($this->it->getPathname());
}
function key() {
return $this->it->getPathname();
}
}
$dir = new RecursiveIteratorIterator(new DirectoryFilterDots(
new RecursiveDirectoryIterator($argv[1])), true);
foreach ($dir as $file) {
print $file. "\n";
}
Expected result:
----------------
Class filters out dot files.
Actual result:
--------------
PHP Notice: Undefined property:
DirectoryFilterDots::$it in /Users/adam/Documents/php/
php5/dir.php on line 42
PHP Fatal error: Call to a member function isDot() on a
