Example#2 Usando un REF CURSOR en una sentencia select

<?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>";
    }
