php - 我怎样才能让我的 php 只从 mysql 返回某个 id

Question

如何让我的 php 页面只返回具有特定 id 的行。我在一个像博客一样设置的网页上工作，我使用 mysql 发帖，我只显示 ID 为 1 的条目，所以我不必担心删除旧帖子或在一页上有 100 个帖子。

        <?php
        include ("includes/includes.php");

        $blogPosts = GetBlogPosts();

        foreach ($blogPosts as $post)
        {
            echo "<div class='post'>";
            echo "<h2>" . $post->title . "</h2>";
            echo "<p>" . $post->post . "</p>";
            echo "<br />";
            echo "<span>Posted By: " . $post->author . "&nbsp Posted On: " . $post->datePosted . "&nbsp Tags: " . $post->tags . "</span>";
            echo "</div>";
        }

        ?>

$result = mysql_query("SELECT * FROM entries WHERE id=1");
