An example outputs wrong

Question

for example:
<?php
create table testtable (
order_number number(4),
item_id number(4),
quantity number(8),
item_desc varchar2(16)
insert into testtable values (1001,1,10,'apple');
insert into testtable values (1001,2,20,'banana');
insert into testtable values (1002,2,50,'banana');
insert into testtable values (1002,1,30,'apple');
insert into testtable values (1003,3,60,'orange');
insert into testtable values (1004,3,50,'orange');
commit;
Table Test DATA
order_number item_id quantity item_desc
1001 1 10 apple
1001 2 20 banana
1002 2 50 banana
1002 1 30 apple
1003 3 60 orange
1004 3 50 orange
$con = oci_connect("apps","apps","prod") or die("Unable to connect oracledatabase");
$sql = "select * from testtable";
$result = oci_parse($con,$sql);
oci_execute($result);
echo "<table border = 1>";
echo "<td>COMPANY</td>";
echo "<td>ORDER_NUMBER</td>";
echo "<td>ITEM_ID</td>";
echo "<td>QUANTITY</td>";
echo "<td>ITEM_DESC</td>";
$totalcomany = 0;
while ($rows = oci_fetch_array($result,OCI_BOTH)) {
if((isset($l_company) and $l_company != $rows['COMPANY']) or empty($result)) {
echo "<tr bgcolor='#CCFFCC'>";
echo "<td colspan= 3 align='center'>".$l_company."</td>";
echo "<td >".$totalcomany." </td>";
$totalcomany = 0;
echo "<td > </td>";
echo "</tr>";
$l_company = $rows['COMPANY'];
echo "<tr>";
echo "<td>".$rows['COMPANY']."</td>";
echo "<td>".$rows['ORDER_NUMBER']."</td>";
echo "<td>".$rows['ITEM_ID']."</td>";
echo "<td>".$rows['QUANTITY']."</td>";
echo "<td>".$rows['ITEM_DESC']."</td>";
$totalcomany = $totalcomany + $rows['QUANTITY'];
echo "</tr>";
echo "</table>";
?>
who can test my above example and you will find its output has a little wrong.
COMPANY A can be calculated sum while COMPANY B not .
who can help me and renew some code about it ?
thanks!

create table testtable (
company varchar2(6),
order_number number(4),
item_id number(4),
quantity number(8),
item_desc varchar2(16)
insert into testtable values ('A',1001,1,10,'apple');
insert into testtable values ('A',1001,2,20,'banana');
insert into testtable values ('A',1002,2,50,'banana');
insert into testtable values ('B',1002,1,30,'apple');
insert into testtable values ('B',1003,3,60,'orange');
insert into testtable values ('B',1004,3,50,'orange');
commit;
Table Test DATA
company order_number item_id quantity item_desc
A 1001 1 10 apple
A 1001 2 20 banana
A 1002 2 50 banana
