Hello all

I need some assistance converting code to use the
RecursiveIterator in PHP 5 SPL. I have the following
function which scans through a nested array set and
returns the path to all matches.

<?php
function arraySearchRecursive($needle, $haystack,
$path="")
{
foreach($haystack as $key=>$value)
{
$path .= "$key/";

// unset the path once the end of the tree is
reached
if (is_array($value))
{
arraySearchRecursive($needle, $value, $path);
unset($path);
}

else
{
echo $path;
}
}
}
?>

I'm trying to convert this to use iterators as I
believe that may be faster/more efficient. However I'm
totally confused as to how to do it given the large
number of interfaces/classes and lack of
documentation. Could someone knowledgeable on the list
help me get started? Ideally I'd like a
framework/outline in pseudocode.

Thanks!

Kam
