Strict Standards: Declaration of API_RATING::multiDelete() should be compatible with API::multiDelete($ids = 0)

Question

I recently moved one of my sites to a new dedicated server running the latest version of PHP. In my php-based Knowledgebase section of the site, I am getting the following error:

Strict Standards: Declaration of API_RATING::multiDelete() should be compatible with API::multiDelete($ids = 0) in /home/givebrad/public_html/kb/lib/api/class.rating.php on line 156

Line 156 is the last closing } at the bottom of the file. Below is the code for class-rating.php. Can anyone help me out to figure out how to fix this?

<?php
require_once(dirname(__FILE__).DIRECTORY_SEPARATOR.'class.api.php');

class API_RATING extends API
{
    var $rateid = 0;
    var $questionid = 0;
    var $ip = '';
    var $ratedat = '';

    var $fields = array (
        'rateid',
        'questionid',
        'ip',
        'ratedat',
        'ratingemail',
        'ratingmessage'
    );

    var $pk = 'rateid';

    /**
    * create
    * create a new rating in the database
    *
    * @return bool was the creation successful ?
    */
    function create()
    {
        $_POST['ratedat'] = date('Y-m-d H:i:s');
        $_POST['ip'] = $_SERVER['REMOTE_ADDR'];
        return parent::create();
    }

    function multiDelete($ids) {

        //Get the question ids
        $objArray = $this->loadMultiByPK($ids);

        foreach ($objArray as $rateObj) {
            $questionObj = new API_QUESTION(); 
            $questionObj->load($rateObj->questionid);

            $questionObj->negvotes--;
            $questionObj->score -= SCORE_MODIFIER;

            $questionObj->updateField("negvotes", $questionObj->negvotes);
            $questionObj->updateField("score", $questionObj->score);
        }           

        //Delete from the main table

This function :

function multiDelete($ids) {

Should be identic with it's parent function, find out the same function in class API, the nums, default value and type of the params should be same;

I asked this before, Strict Standards: Declaration of ' ' should be compatible with ' '
