Oracle queries using PHP

I've got some troubles running combined queries using PHP:

I have two tables, "patients" and "appointments".
In the appointments-table there is a key AP_PATKEY which is the link to the key P_KEY in the table patients.
Purpose is to look which appointment has been changed (AP_DATECHANGED in appointments) and to return
the name of the patient (P_NAME in patients).

However, when I combine the query in PHP, I'v got the following errors:

Warning: ociexecute(): OCIStmtExecute: ORA-03106: fatal two-task communication protocol error in test2.php on line 20

Warning: ocifetch(): OCIFetch: ORA-24374: define not done before fetch or execute and fetch in test2.php on line 38

Source code is below:

<html>
<head>
<meta http-equiv="Content-Language" content="nl-be">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Overview today changed appointments</title>
</head>
<body topmargin="0" leftmargin="0" rightmargin="0" bottommargin="0">
<?php
$thisday = date("d-M-y");
$database = $dbase;
$userid = "xxx";
$paswd = "xxx";
putenv('ORACLE_HOME=/home/oracle/Ora9204');
$mycon = OCILogon($userid, $paswd, $database);
$cursor = OCIParse($mycon, "SELECT a.AP_KEY, a.AP_DATE, a.AP_PATKEY, a.AP_DATEMADE, a.AP_DATECHANGED,
a.AP_REQUESTEDBY_COM, p.P_KEY, p.P_NAME FROM appointments a, patients p WHERE a.AP_DATECHANGED >= '$thisday' AND
a.AP_DATE = '$thisday' AND a.AP_PATKEY = p.P_KEY");
OCIExecute ($cursor, OCI_DEFAULT);
?>
Overview (changed)
appointments today (on <? echo $database ?>):
Current date is: <? echo $thisday ?>
List of changed appointments for today:
<table border="1" width="100%" style="font-family: Verdana; font-size: 10pt; color: #0000FF" bgcolor="#C0C0C0">
<tr>
<td align="center">AP_KEY</td>
<td align="center">AP_DATE</td>
<td align="center">AP_PATKEY</td>
<td align="center">P_NAME</td>
<td align="center">AP_DATEMADE</td>
<td align="center">AP_DATECHANGED</td>
<td align="center">AP_REQUESTEDBY_COM</td>
</tr>
<?php
$teller = 1;
while (OCIFetch($cursor))
{
$apdat[$teller] = ociresult($cursor, "AP_DATE");
$key[$teller] = ociresult($cursor, "AP_KEY");
$identification[$teller] = ociresult($cursor, "AP_PATKEY");
$creadat[$teller] = ociresult($cursor, "AP_DATEMADE");
$datchanged[$teller] = ociresult($cursor, "AP_DATECHANGED");
$requestor[$teller] = ociresult($cursor, "AP_REQUESTEDBY_COM");
$patname[$teller] = ociresult($cursor, "P_NAME");
?>
<tr>
<td><? echo $key[$teller]; ?></td>
<td><? echo $apdat[$teller]; ?></td>
<td><? echo $identification[$teller]; ?></td>
<td><? echo $patname[$teller]; ?></td>
<td><? echo $creadat[$teller]; ?></td>
<td><? echo $datchanged[$teller]; ?></td>
<td><? echo $requestor[$teller]; ?></td>
</tr>
<?php
$teller = $teller + 1;
}
OCILogoff($mycon);
?>

</table>
<?php
?>
</body>
</html>

What do I do wrong?

Thanks in advance for any help.

Eric
