The reason about php code

Question

for example:
create table testtable (
order_number number(40),
item_id number(40),
quantity number(20),
item_desc varchar2(50)
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');
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
if I insert into testtable below new line :
insert into testtable values (3020002506,242,5,'580gcreamery1x10');
why below example doesn't work?
<?php
$table ="testtable";
//$sid="(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=202.79.36.170)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=WLDB)))";
$conn = ocilogon("apps", "apps", "prod");
$sql="select distinct(item_desc) item_desc from $table";
$stmt = oci_parse ($conn, $sql);
oci_execute ($stmt);
$items=array();
$result= array();
$i=0;
while ($result = oci_fetch_array($stmt,OCI_BOTH)) {
$items[$i]=$result['ITEM_DESC'];
// echo $result['ITEM_DESC'];
$i=$i+1;
//build part of select stateme
for ($i=0; $i<sizeof($items); $i++) {
$select_items .= "SUM($items[$i]) $items[$i],";
for ($i=0; $i<sizeof($items); $i++) {
$decode_items .= "DECODE(item_desc,'$items[$i]', quantity, null) $items[$i],";
//final SQL statement
$sql="SELECT $select_items order_number
FROM (SELECT $decode_items order_number FROM $table )
group by order_number";
$stmt=oci_parse ($conn, $sql);
oci_execute($stmt);
echo "<table border=1>";
echo "<tr>";
echo "<td>Order Number</td>";
for ($i=0; $i<sizeof($items); $i++) {
echo "<td>".$items[$i]." </td>";
echo "</tr>";
while ($row = oci_fetch_array ($stmt, OCI_BOTH)) {
echo "<tr>";
echo "<td>".$row['ORDER_NUMBER']."</td>";
for ($i=0; $i<sizeof($items); $i++) {
echo "<td>".$row[$i]." </td>";
echo "</tr>";
echo "</table>";
?>
who can help me?
thanks!

Try this...
I modified code a little, because your PHP-style is not too exellent :( (newbie?), but this code is equivalent to your original posted... The difference is in output part. Look at this part more attentive!
<?php
$table ="testtable";
$sql="select distinct(item_desc) item_desc from $table";
if ($conn = ocilogon("apps", "apps", "prod")) oci_execute (oci_parse ($conn, $sql));
else die ("Connection error!");
$items=array(); $result= array(); $i=0;
while ($result = oci_fetch_array($stmt,OCI_BOTH)) $items[]=$result['ITEM_DESC'];
//build part of select stateme
$select_items = ''; $decode_items = '';
foreach ($items AS $item) {
$select_items .= "SUM($item) $item,";
$decode_items .= "DECODE(item_desc,'$item', quantity, null) $item,";
//final SQL statement
$sql="
SELECT $select_items order_number
FROM (SELECT $decode_items order_number FROM $table )
GROUP BY order_number
if ($conn) oci_execute(oci_parse ($conn, $sql));
else die ("Connection error!");
echo "<table border=1>";
echo "<tr>";
echo "<td>Order Number</td>";
foreach ($items AS $item) echo "<td>$item</td>";
echo "</tr>";
while ($row = oci_fetch_array ($stmt, OCI_BOTH)){
echo "<tr>";
echo "<td>".$row['ORDER_NUMBER']."</td>";
for ($i=0; $i<sizeof($items); $i++) {
// echo "<td>".$row[$i]." </td>";
// Maybe you mean $row[$item] ???
echo "<td>".$row[$item]." </td>";
echo "</tr>";
echo "</table>";
?>
