Yes, or alternatively you could extend an existing helper. For instance, if you're already using the HTML helper, you could just create a "MY_html_helper.php" file in your system/application/helpers directory and define the function there. Then when you do your "$this->load->helper('html');", it will include your new function with it.
It may not be a pure OOP solution, but it would seem pretty clean, simple, and efficient to me.
