oci_num_fields() returns the number of columns in the statement.

Example 1. oci_num_fields() example
`<?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 .

> Note: 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.
