Question

经过艰苦的努力之后，我终于能够在我的index.php中显示博客条目了，但订购的是最新的博客条目，而较旧的条目位于最顶层。

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＆＃34;命令＆＃34;您希望将它们列为的时尚数据，您可以使用
ORDER BY your_column可以选择ASC或DESC。

如果从查询中省略，则

ORDER BY默认为ASC。

I.e。：

SELECT * FROM posts ORDER BY titulo DESC

请教：

从手册中摘录的例子：

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], ...]
