    例1 cubrid_col_get() 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);

    $size = cubrid_col_size($conn, $oid, "b");
    var_dump($size);

    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"
}
int(3)
