    Example #1 cubrid_lock_write() 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($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");
    cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(2, {4,5,7}, {44,55,66,666}, 'b')");

    $req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);

    cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
    $oid = cubrid_current_oid($req);

    cubrid_lock_write($conn, $oid);

    $attr = cubrid_col_get($conn, $oid, "b");
    var_dump($attr);

    cubrid_put($conn, $oid, "b", array(2, 4, 8));

    $attr = cubrid_col_get($conn, $oid, "b");
    var_dump($attr);

    cubrid_close_request($req);
    cubrid_disconnect($conn);
    ?>

    The above example will output:

    array(3) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" } array(3) { [0]=> string(1) "2" [1]=> string(1) "4" [2]=> string(1) "8" }
