php - deep search array of arrays and return only matching elements

Question

I am looking for a solution in php as mentioned in the accepted answer of this question:

javascript - return parent with only child that matches given s

Answer 1

I was looking to return a result based on an exact match so have modified Manish's answer below with a third parameter of strict. Passing true will return an exact match only.

public function getParentStackComplete($search, $stack, $strict = false)
{
    $results = array();

    foreach ($stack as $item) {

        if (is_array($item)) {

            if (array_filter($item, function ($var) use ($search) {
                return (!is_array($var)) ? stristr($var, $search) : false;
            })) {
                //echo 'test';
                $results[] = $item;

                if ($strict) {
                    if ($item['name'] === $search)
                        return $item;
                }

                continue;
            } else if (array_key_exists('asset_info', $item)) {
                $find_assets = array();
                foreach ($item['asset_info'] as $k => $v) {
                    //echo 'abc ';

                    if (is_array($v) && array_filter($v, function ($var) use ($search) {
                            return stristr($var, $search);
                        })) {
                        $find_assets[] = $v;
                    }
                }
                if (count($find_assets)) {
                    $temp = $item;
                    $temp['asset_info'] = $find_assets;
                    $results[] = $temp;
                }

            }
        }
    }

    return $results;
}
