<?php
// suppose your stored procedure info.output returns a ref cursor in :data
$conn = oci_connect("scott", "tiger");
$curs = oci_new_cursor($conn);
$stmt = oci_parse($conn, "begin info.output(:data); end;");
oci_bind_by_name($stmt, "data", $curs, -1, OCI_B_CURSOR);
oci_execute($stmt);
oci_execute($curs);
while ($data = oci_fetch_row($curs)) {
var_dump($data);
}
oci_free_statement($stmt);
oci_free_statement($curs);
oci_close($conn);
?>

例子 2. Using REF CURSOR in an Oracle's select statement
<?php
echo "<html><body>";
$conn = oci_connect("scott", "tiger");
$count_cursor = "CURSOR(select count(empno) num_emps from emp " .
"where emp.deptno = dept.deptno) as EMPCNT from dept";
$stmt = oci_parse($conn, "select deptno,dname,$count_cursor");
oci_execute($stmt);
echo "<table border=\"1\">";
echo "<tr>";
echo "<th>DEPT NAME</th>";
echo "<th>DEPT #</th>";
echo "<th># EMPLOYEES</th>";
echo "</tr>";
while ($data = oci_fetch_assoc($stmt)) {
echo "<tr>";
$dname = $data["DNAME"];
$deptno = $data["DEPTNO"];
echo "<td>$dname</td>";
echo "<td>$deptno</td>";
oci_execute($data["EMPCNT"]);
while ($subdata = oci_fetch_assoc($data["EMPCNT"])) {
$num_emps = $subdata["NUM_EMPS"];
echo "<td>$num_emps</td>";
}
echo "</tr>";

oci_new_cursor() returns FALSE on error.
注:
In PHP versions before 5.0.0 you must use ocinewcursor() instead.
This name still can be used, it was left as alias of
oci_new_cursor() for downwards compatability.
This, however, is deprecated and not recommended.
