Creating variable tree in php for javascript to read (NOOB)

I am trying to duplicate the variable tree that starts at line 52 via php rather than hard coding it. I am able to generate the top level (school), now I figured I could put another loop in the do while statement, but I am getting an infinite loop. I have tried a million ways to do this, but to no avail.
I also have a feeling there is a way I can do this with one db query.

Any help would be appreciated.

This worked:
<br /><script language="JavaScript">
totalR = 9;
var schools = new Array();
aa:{
ahs:{
biz:{
dent:{
edu:{
eng:{
las:{
n:{
up:{
</script>

Adding the loop went awry:

<br /><script language="JavaScript">
totalR = 9;
var schools = new Array();
aa:{

do {
....
do {
...
} while ($row_Recordset2['deptName_id'] = $row_Recordset1['deptName_id']);
} while ($row_Recordset1 = mysql_fetch_assoc($Recordset1));

I think this is equal all the time
$row_Recordset2['deptName_id'] = $row_Recordset1['deptName_id']
and so the infinite loop

I'm not yet sure about this (still trying to decode the snippet :P) but this seems to be the problem.

Sorry if it is a mess(>.<); Here is a sample of the table data:

deptName_id| major_id| sYear| qGrad
ahs|      Health Information Mgmt.|      2004|      17
ahs|      Kinesiology|      2004|      78
ahs|      Nutrition|      2004|      18
ahs|      Phys. Ed.|      2004|      0
aa|      Architectural Studies|      2004|      92

Thanks. It was a long shot, I was notable to get the visualization with protovis, so I was not sure if that did it. Cheers.
