Esempio 1. Using a REF CURSOR from a stored procedure

    <?php
    // suppose your stored procedure info.output returns a ref cursor in :data

    $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);
    ?>

Esempio 2. Using a REF CURSOR in a select statement

    <?php
    print "<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);
    print "<TABLE BORDER=\"1\">";
    print "<TR>";
    print "<TH>DEPT NAME</TH>";
    print "<TH>DEPT #</TH>";
    print "<TH># EMPLOYEES</TH>";
    print "</TR>";

    while (OCIFetchInto($stmt,&$data,OCI_ASSOC)) {
        print "<TR>";
        $dname  = $data["DNAME"];
        $deptno = $data["DEPTNO"];
        print "<TD>$dname</TD>";
        print "<TD>$deptno</TD>";
        ociexecute($data["EMPCNT"]);
        while (OCIFetchInto($data["EMPCNT"],&$subdata,OCI_ASSOC)) {
            $num_emps = $subdata["NUM_EMPS"];
            print  "<TD>$num_emps</TD>";
        }
        print "</TR>";
    }
    print "</TABLE>";
    print "</BODY></HTML>";
    OCIFreeStatement($stmt);
    OCILogoff($conn);
    ?>
