我正在尝试创建一个PHP api,我正在尝试检索新闻故事及其所有注释并将其作为json发送。
这是我到目前为止所拥有的:
$sql = "SELECT * FROM fb_clubnews WHERE clubid='$groupId' AND ori_newsid = 0 ORDER BY newsid DESC LIMIT 10";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$storId = $row["newsid"];
$commentArray = array();
$wallAray[] = array("author"=>$row["userid"],
"story"=>$row["news"],
"date"=>$row["date"],
"time"=>$row["time"],
"matchid"=>$row["fk_match_id"],
"comments"=>$commentsArray);
}
}
我的问题是,我想避免在sql中创建一个sql并循环遍历它?!第二个内部sql是:
$sql = "SELECT * FROM fb_clubnews WHERE ori_newsid = $storId ORDER BY newsid DESC";
如何让$ commentArray充满评论。
fb_clubnews的我的数据库结构如下所示:
int newsid (autoincrement),
int userid,
text news,
int data,
int time,
int matchid,
int ori_newsid
希望得到帮助,并提前感谢: - )

这样的事情:
$sql = "SELECT *, A.newsid as main_news_id FROM fb_clubnews A LEFT JOIN fb_clubnews B ON B.ori_newsid = A.newsid WHERE A.clubid='$groupId' AND A.ori_newsid = 0 ORDER BY A.newsid DESC";
$result = $conn->query($sql);
$wallAray = array();
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$storId = $row["main_news_id"];
if(array_key_exists($storId, $wallAray)) {
$commentArray[] = $wallAray;
} else {
$wallAray[$storId] = array();
$commentArray = array();
}
$wallAray[] = array("author"=>$row["userid"],
"story"=>$row["news"],
"date"=>$row["date"],
"time"=>$row["time"],
"matchid"=>$row["fk_match_id"],
"comments"=>$commentsArray);
}
}
