如何在<option>标签上显示多个值？

I have a select list with a number of option tags. For each option tag, I want to display multiple values to the user.

<option value="' . $location['locationId'] . '">' . $location['locationName'] . '</option>

Instead of only displaying the $location['locationName'], I would like to display values contained to that location, ex: $location['city'], $location['province']

I can't seem to find a way to display this in an appealing way.

Here is my select list in complete:

<select class="form-control" size="10" name="locationId">';
    foreach ($locations as $location) {
        $pageContent[] = '<option value="' . $location['locationId'] . '">' . $location['locationName'] . '</option>';
    }
    $pageContent[] = '</select>
