按升序（时间）对我的 post 进行排序

Question

经过一番努力，我终于能够在我的 index.php 中显示博客条目，但是它们的顺序是新的在底部，旧的在顶部。

这是我的代码：

<?php
            $connect = new PDO('mysql:host=localhost;dbname=posts','root','');

            $cmd = $connect->query('SELECT * FROM posts');

            $resultado = $cmd->fetchAll(PDO::FETCH_ASSOC);

             foreach($resultado as $item):
                ?>
                <div class="post">
                    <div class="post-body">
                        <a href="" class="post-title"><?php echo $item['titulo']?></a>
                        <div class="title-separator"></div>
                        <p class="post-body-text"><?php echo $item['cuerpo'] ?></p>
                    </div>
                    <div class="post-body-footer">
                        <img src="images/posted.png" alt="" class="posted"> <span class="posted-text">Posted on </span><span class="date"><?php echo $item['fecha']?></span>
                    </div>
                </div>
                <?php
             endforeach;
        ?>

为了"order"您的数据以您希望的方式列出，您可以使用
ORDER BY your_column 可选择 ASC 或 DESC。

如果在查询中省略，

ORDER BY 默认为 ASC。

即：

SELECT * FROM posts ORDER BY titulo DESC

咨询：

https://dev.mysql.com/doc/refman/5.0/en/select.html

手册中的示例：

SELECT
    [ALL | DISTINCT | DISTINCTROW ]
      [HIGH_PRIORITY]
      [STRAIGHT_JOIN]
      [SQL_SMALL_RESULT] [SQL_BIG_RESULT] [SQL_BUFFER_RESULT]
      [SQL_CACHE | SQL_NO_CACHE] [SQL_CALC_FOUND_ROWS]
    select_expr [, select_expr ...]
    [FROM table_references
    [WHERE where_condition]
    [GROUP BY {col_name | expr | position}
      [ASC | DESC], ... [WITH ROLLUP]]
    [HAVING where_condition]
    [ORDER BY {col_name | expr | position}
      [ASC | DESC], ...]

按升序（时间）对我的 post 进行排序
