`<?php $conn = oci_connect("scott", "tiger"); $stmt = oci_parse($conn, "SELECT * FROM emp"); oci_execute($stmt); echo "<table border=\"1\">"; echo "<tr>"; echo "<th>Name</th>"; echo "<th>Type</th>"; echo "<th>Length</th>"; echo "</tr>"; $ncols = oci_num_fields($stmt); for ($i = 1; $i <= $ncols; $i++) { $column_name = oci_field_name($stmt, $i); $column_type = oci_field_type($stmt, $i); $column_size = oci_field_size($stmt, $i); echo "<tr>"; echo "<td>$column_name</td>"; echo "<td>$column_type</td>"; echo "<td>$column_size</td>"; echo "</tr>"; } echo "</table>"; oci_free_statement($stmt); oci_close($conn); ?>`

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