尝试显示PhpBB安装中的六篇最新帖子。我对它的工作方式很满意，但它显示了同一（最近的）帖子的六份副本，而不是唯一的最新帖子。
只是为了确认一下，我在论坛上总共有七个帖子。
<?php
$con = mysqli_connect("localhost", "dbuser", "dbpass", "dbname");
$users = mysqli_query($con, "SELECT * FROM phpbb_user_group WHERE group_id='8'");
while($row = mysqli_fetch_array($users)) {
$developers[] = $row["user_id"];
}
$post = mysqli_query($con, "SELECT * FROM phpbb_posts");
while($row = mysqli_fetch_array($post)) {
$topic_id = $row["topic_id"];
$forum_id = $row["forum_id"];
$post_id = $row["post_id"];
$post_text = $row["post_text"];
$post_time = $row["post_time"];
}
$username = mysqli_query($con, "SELECT * FROM phpbb_users WHERE user_id='2'");
while($row = mysqli_fetch_array($username)) {
$postauthor = $row["username"];
if (strlen($post_text) > 10)
$post_text = wordwrap($post_text, 120);
$post_text = explode("'n", $post_text);
$post_text = $post_text[0] . '...';
$result = mysqli_query($con, "SELECT * FROM phpbb_posts WHERE poster_id='2' LIMIT 6");
while($row = mysqli_fetch_array($result)) {
$content = '<div onclick="location.href=''http://test.mythros.net/forum/viewtopic.php?f=' . $forum_id . '&p=' . $topic_id . '#p' . $post_id . ''';" class="forum-latest-box">';
$content .= '<div class="forum-latest-userbar">';
$content .= '<div class="forum-latest-avatar">';
$content .= '<img src="https://minotar.net/helm/' . $postauthor . '/40.png">';
$content .= '</div>';
$content .= '<h1>' . $postauthor . '</h1>';
$content .= '</div>';
$content .= '<div class="forum-latest-content">';
$content .= '<div class="forum-latest-text">';
$content .= '"' . $post_text . '"';
$content .= '</div>';
$content .= '<div class="forum-latest-meta">';
$content .= gmdate("F j, Y, g:i a", $post_time);
$content .= '</div>';
$content .= '</div>';
$content .= '</div>';
echo $content;
}
?>
您可以通过使用单个循环来解决此问题，并使用对phpbb_posts表和phpbb_users表的组合查询来同时获取您的帖子数据和用户信息：
## Line break added to the query for legibility
$result = mysqli_query($con,
"SELECT
p.post_id AS post_id,
p.topic_id AS topic_id,
p.forum_id AS forum_id,
p.post_time AS post_time,
p.post_subject AS subject,
p.post_text AS post_text
IFNULL(m.username, 'Guest') AS username,
FROM phpbb_posts AS p
LEFT JOIN phpbb_users AS m ON (m.user_id = p.poster_id)
ORDER BY phpbb_posts.post_time DESC LIMIT 6");
while($row = mysqli_fetch_array($result)) {
# $row now contains the post information and the user info, so you can grab all your data,
# process the post text, and print it out at the same time.
$post_text = $row["post_text"];
# do your text transformation
if (strlen($post_text) > 10)
... (etc.)
# now set up your content
$content = '<div onclick="location.href=''http://test.mythros.net/forum/viewtopic.php?f=' . $row["forum_id"] .'&p=' . $row["topic_id"] . '#p' . $row["post_id"] . ''';" class="forum-latest-box">';
