right but the collection is built during iteration. one thing you could do
if you wanted it to *appear* as though the count was there at construction
is to subclass and iterate once in the constructor.
something like this:
<?php
class SmartDirectoryIterator extends DirectoryIterator implements Countable
{
private $_iCount = 0;
public function __construct($sPath)
{
parent::__construct($sPath);
foreach($this as $oFile)
if($oFile->isFile())
$this->_iCount++;
}
public function count()
{
return $this->_iCount;
}
?>
