Example #1 cubrid_field_len() example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$result = cubrid_execute($conn, "SELECT * FROM game WHERE host_year=2004 AND nation_code='AUS' AND medal='G'");
$column_names = cubrid_column_names($result);
$column_types = cubrid_column_types($result);
printf("%-30s %-30s %-15s\n", "Column Names", "Column Types", "Column Maxlen");
for($i = 0, $size = count($column_names); $i < $size; $i++) {
$column_len = cubrid_field_len($result, $i);
printf("%-30s %-30s %-15s\n", $column_names[$i], $column_types[$i], $column_len);
}
cubrid_disconnect($conn);
?>`
