Example 1. Using REF CURSOR in an Oracle's stored procedure


<?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);
?>

Example 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>";
}
echo "</table>";
echo "</body></html>";
oci_free_statement($stmt);
oci_close($conn);
?>

oci_new_cursor() returns FALSE on error.

Note: 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.
