`<?php
echo "<pre>\n";
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "select * from emp");
oci_execute($stmt);
while (oci_fetch($stmt)) {
echo "\n";
$ncols = oci_num_fields($stmt);
for ($i = 1; $i <= $ncols; $i++) {
$column_name = oci_field_name($stmt, $i);
$column_value = oci_result($stmt, $i);
echo $column_name . ': ' . $column_value . "\n";

oci_num_fields() returns `FALSE` on error.

> Nota: In PHP versions before 5.0.0 you must use ocinumcols() instead. This name still can be used, it was left as alias of oci_num_fields() for downwards compatability. This, however, is deprecated and not recommended.
