例1 cubrid_set_add() example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
@cubrid_execute($conn, "DROP TABLE foo");
cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);
cubrid_set_add($conn, $oid, "b", "4");
$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>`

上の例の出力は以下となります。

    array(3) {
      [0]=>
      string(1) "1"
      [1]=>
      string(1) "2"
      [2]=>
      string(1) "3"
    }
    array(4) {
      [0]=>
      string(1) "1"
      [1]=>
      string(1) "2"
      [2]=>
