### 范例

Example #1 cubrid_affected_rows() example

    <?php
    $conn = cubrid_connect('localhost', 33000, 'demodb', 'dba', '');
    cubrid_execute($conn, "DROP TABLE IF EXISTS cubrid_test");
    cubrid_execute($conn, "CREATE TABLE cubrid_test (d varchar)");
    $sql_stmt = "INSERT INTO cubrid_test(d) VALUES('php-test')";
    $req = cubrid_prepare($conn, $sql_stmt);

    for ($i = 0; $i < 10; $i++) {
        cubrid_execute($req);
    }
    cubrid_commit($conn);

    $req = cubrid_execute($conn, "DELETE FROM cubrid_test WHERE d='php-test'", CUBRID_ASYNC);
    var_dump(cubrid_affected_rows());
    var_dump(cubrid_affected_rows($conn));
    var_dump(cubrid_affected_rows($req));

    cubrid_disconnect($conn);

    print "done!";
    ?>

以上例程会输出：

    Rows deleted: 5
