Runtime is too long

Question

how to make php code run faster?
for example :
part php code:
while ($row = oci_fetch_array ($stmt, OCI_BOTH)) {
echo "<tr>";
echo "<td>".$row['SEGMENT1']."</td>";
echo "<td>".$row['SEGMENT2']."</td>";
echo "<td>".$row['ORDER_NUMBER']."</td>";
who can give me some good advice?

hi
ushastry
thanks
is there any good way to improve below example run faster or to rewrite it in another way ?
<?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');
commit;
Table Test DATA
order_number item_id quantity item_desc
