PHP find array key recursively
Today I had an issue where I needed to find a key in multidimensional array. It
took trial and error ant some googling around, but this is what I found.
<php
function recursiveFind(array $haystack, $needle)
{
$iterator = new RecursiveArrayIterator($haystack);
$recursive = new RecursiveIteratorIterator(
$iterator,
RecursiveIteratorIterator::SELF_FIRST
);
foreach ($recursive
