I found this from php manual under the key() functions comments. This should do it.

 

<?php
    // array_key_relative - Returns a key in an associative array relative to another key without using foreach. Very useful for finding previous key or finding next key in array, etc

    // function array_key_relative(array $array, string $current_key, int $offset)
    function array_key_relative($array, $current_key, $offset = 1) {
        // create key map
        $keys = array_keys($array);
        // find current key
        $current_key_index = array_search($current_key, $keys);
        // return desired offset, if in array, or false if not
        if(isset($keys[$current_key_index + $offset])) {
            return $keys[$current_key_index + $offset];
        }
        return false;
    }
?>
