$conn = OCILogon("scott", "tiger");
$curs = OCINewCursor($conn);
$stmt = OCIParse($conn, "begin info.output(:data); end;");

ocibindbyname($stmt, "data", &$curs, -1, OCI_B_CURSOR);
ociexecute($stmt);
ociexecute($curs);

while (OCIFetchInto($curs, &$data)) {
    var_dump($data);
}

OCIFreeStatement($stmt);
OCIFreeCursor($curs);
OCILogoff($conn);
?>

Example 2. Using a REF CURSOR in a select statement in Oracle

<?php   
echo "<html><body>";
$conn = OCILogon("scott", "tiger");
$count_cursor = "CURSOR(select count(empno) num_emps from emp " .
                "where emp.deptno = dept.deptno) as EMPCNT from dept";
$stmt = OCIParse($conn, "select deptno,dname,$count_cursor");

ociexecute($stmt);
echo "<table border=\"1\">";
echo "<tr>";
echo "<th>DEPT NAME</th>";
echo "<th>DEPT #</th>";
echo "<th># EMPLOYEES</th>";
echo "</tr>";

while (OCIFetchInto($stmt, &$data, OCI_ASSOC)) {
    echo "<tr>";
    $dname  = $data["DNAME"];
    $deptno = $data["DEPTNO"];
    echo "<td>$dname</td>";
    echo "<td>$deptno</td>";
    ociexecute($data["EMPCNT"]);
    while (OCIFetchInto($data["EMPCNT"], &$subdata, OCI_ASSOC)) {
        $num_emps = $subdata["NUM_EMPS"];
        echo  "<td>$num_emps</td>";
    }
    echo "</tr>";
