Problem w/ PHP tutorial ... duplicate data

Question

Hi --
I have got Oracle XE installed okay and it's running fine.
Now I am going thru the PHP tutorial: http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25317/toc.htm
In Chapter 3 (http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25317/ch3.htm#sthref172), I copied the PHP files to my machine and they are running fine except that the "SELECT * FROM DEPARTMENTS" statement produces duplicate data for each column in the table, e.g.:
10,10,Administration,Administration,200,200,1700,1700
20,20,Marketing,Marketing,201,201,1800,1800
30,30,Purchasing,Purchasing,114,114,1700,1700
Any idea why the "oci_fetch_array($stid, OCI_RETURN_NULLS)" statement would return two copies of each of the columns?
When I look at the same table using SQLplus, there are no problems.
Thanks!
Gary

Here is the PHP code that is causing the problem (copied exactly from tutorial):
<?php // File: anyco.php
require('anyco_ui.inc');
// Create a database connection
$conn = oci_connect('hr', 'hr', '//localhost/XE');
ui_print_header('Departments');
do_query($conn, 'SELECT * FROM DEPARTMENTS');
ui_print_footer(date('Y-m-d H:i:s'));
// Execute query and display results
function do_query($conn, $query)
$stid = oci_parse($conn, $query);
$r = oci_execute($stid, OCI_DEFAULT);
print '<table border="1">';
while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {
print '<tr>';
foreach ($row as $item) {
print '<td>'.
($item ? htmlentities($item) : ' ').'</td>';
print '</tr>';
print '</table>';
?>
