PHP: Search an array of object for nested property values

Array search

<?php
/**
 * Search an array for nested property values
 * @param array $array The array you're searching over, perhaps something like
 *  $people = array(
 *    array('name' => 'Bill', 'residence' => array('state' => 'NJ', 'zip' => '07701')),
 *    array('name' => 'Anne', 'residence' => array('state' => 'NJ', 'zip' => '07850')),
 *    array('name' => 'Evan', 'residence' => array('state' => 'NY', 'zip' => '10001'))
 *  )
 * @param array $filters An associative array of filters to match, like
 *  $filters = array('residence.state' => 'NJ', 'residence.zip' => '07850')
 *  .. Which would return Anne.
 *  Filters can go any number of properties deep, including arrays or objects
 * @param mixed $default The value to pass back if no items are found
 * @return array The search results

Thanks for the snippet! Just a notice; you need to add a closing bracket at the very end.
