Code:

/**
     * Clean the file name for security
     *
     * @access    public
     * @param    string
     * @return    string
     */        
    function clean_file_name($filename)
    {
        $bad = array(
                        "<!--",
                        "-->",
                        "'",
                        "<",
                        ">",
                        '"',
                        '&',
                        '$',
                        '=',
                        ';',
                        '?',
                        '/',
                        " ",
                        """,
                        "<",        // <
                        "%3c",     // <
                        ">",         // >
                        "",         // >
                        "(",         // (
                        ")",         // )
                        "%28",     // (
                        "&",         // &
                        "$",         // $
                        "?",         // ?
                        ";",         // ;
                        "="        // =
                    );
                    
        foreach ($bad as $val)
        {
            $filename = str_replace($val, '', $filename);
        }

        return stripslashes($filename);
    }

Would it not be better to just pass the $bad variable as the first parameter like so?:

Code:

str_replace($bad, '', $filename);

Thus avoiding the need for the loop.
