在while循环中查询

Question

我有这个查询电话：

$currplayer = 1;

$query = "SELECT f.fk_user_id2, u.username, u.profileimg FROM ".$prefix."_friends f 
                        INNER JOIN ".$prefix."_users u
                            ON f.fk_user_id2 = u.id     
                    WHERE f.fk_user_id1 = $currplayer ORDER BY u.username ASC";

if ($result = $mysqli->query($query)){
    while ($row1 = $result->fetch_assoc()){

        $friendid = $row1['fk_user_id2'];

        $sql = $mysqli->query("SELECT * FROM ".$prefix."_newversus WHERE fk_player=$currplayer AND fk_opponent=$friendid");
        $row = $sql->fetch_assoc();

我试图弄清楚如何在循环内将查询带入带有内部联接的第一个查询中，但无法解决。

希望获得帮助并提前表示感谢:-)

如果我正确地找到了您，则想删除循环运行的查询并将其添加到主查询中。

尝试这个：

SELECT f.fk_user_id2, u.username, u.profileimg FROM ".$prefix."_friends f 
INNER JOIN ".$prefix."_users u ON f.fk_user_id2 = u.id 
INNER JOIN ".$prefix."_newversus n ON f.fk_user_id2 = n.fk_opponent 
WHERE f.fk_user_id1 = $currplayer AND
n.fk_player=$currplayer
ORDER BY u.username ASC;
