I got around this problem by using is_object() and is_array().

When you search for a single element, an object is returned. When you search for a set of elements, an array of objects is returned.

$td = $html->find("td", 23) is searching for a single element, so using the following will check for the existence of the searched-for element:

$td = $html->find("td", 23);
if (is_object($td)) {
    //continue
}
