例1 cubrid_lock_write() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
@cubrid_execute($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);
?>

string(1) "2"
[2]=>
string(1) "3"
}
