PHP Dynamically returning multidimensional arrays

I have been doing a lot of work in learning how to return multidimensional arrays dynamically- but what I can't seem to figure out is how to nest them.

I have two tables, each has the identical format: ID, name.

Table one: SSC - sscid - sscname

Table two: SRV - srvid - srvname

What I am trying to do is print all of the items in table two under EACH item in the table one list.

The table one items are the headers, the table two items are returned as a checkbox (with the srvid as the value) and label(srvname).

I can get it to all print together, but it is a. one giant list of results and it's in a

| checkbox | table 1: name | table 2: name | format. 

Not pretty at all (although it is progress for me to get this far).

After I run my query and get the result, my code looks like this:

Now, I've had a few additional thoughts about the design of the concept re:the database tables go, but everything I read indicates that they really need to be on their own tables, and they should be able to be referenced by the key from one table and the key from the other (eventually ended up in a joint table with user ID references) Because they are numerically indexed, I don't know why this would be an issue for me; however I simply can't seem to get this to work properly.

I should mention that when I alter the code to try to make the ssc_name span 2 cols and make it more like a header, it returns a header row for each checkbox/srv row, instead of for all of the checkbox/srv rows.

if($result) {
    echo '<table border="1" align="center" cellspacing="3" cellpadding="3" width="300">
    <tr><th colspan="2"><h3>Options</h3></th></tr>
    <tr><td></td><td align="left"><b>Services</b></td></tr>';
    $numfields = mysql_num_fields($result);
    $data = array();
    $flist = array();
    for($i=0;$i<$numfields;$i++)$flist[] = mysql_field_name($result,$i);
    $data[0] = $flist;
    while($row = mysql_fetch_assoc($result)) {
        $data[] = $row;
        echo '<tr><td colspan="2" align="center"><b>' . $row['ssc_name'] .'</b><td></tr>
        <tr><td align="center"><input type="checkbox" value="'. $row['ssv_id'] .'" / </td>
        <td align="left">' . $row['ssvname'] . '</td>
        </tr>';
    }
    echo '</table>';
}

Can anyone help me figure this out, please?
