Question

另一个Array_multisort帖子对我没有帮助。我按名称排序了2个数组。当我使用array_multisort时，它会按ID进行排序。我怎样才能解决这个问题？我正在使用Joomla 2.5。提前谢谢。

$query = "SELECT DISTINCT(t.id) as id,
                 t.t_name as name, t.t_city as city,
                 (count(pd.rs)) as pdc
    FROM #__bl_teams as t
    JOIN #__bl_paid as pd ON pd.t_id = t.id
        AND pd.rs=1 AND ((MID(pd.r_date,1,10)) >= t.start_date)
    WHERE (t.id IN($teams)) GROUP BY t.id ORDER BY t.t_name ASC";

$db - > setQuery($query);
$players1 = $db - > loadObjectList();

///----same query as above, but return array of team Id's---///

    $query = "SELECT DISTINCT(t.id)
    FROM #__bl_teams as t 
    JOIN #__bl_paid as pd ON pd.t_id = t.id AND pd.rs=1 AND ((MID(pd.r_date,1,10)) >= t.start_date)
    WHERE (t.id IN($teams)) 
    GROUP BY t.id ORDER BY t.t_name ASC";
    $db->setQuery($query);
    $players1a = $db->loadResultArray();

    $players3 = implode(',',$players1a); 

///---------------------------------------------------------///

    $query = "SELECT DISTINCT(t.id) as id, t.t_name as name, t.t_city as city
    FROM #__bl_teams as t 
    WHERE (t.id IN($teams)) AND (t.id NOT IN($players3))
    GROUP BY t.id ORDER BY t.t_name ASC";
    $db->setQuery($query);
    $players2 = $db->loadObjectList();

    $players = array_merge($players1,$players2);


if ($players) {
    $play1 = array();
    foreach($players as $play) {
        $play1[] = $play - > name;
    }
}
array_multisort($play1, SORT_ASC, $players);

var_dump($players);

我认为array_multisort()不会像您认为的那样有效。

您希望按name对查询返回的值进行排序，对吗？在这种情况下，您要寻找的是usort()：

...

$players = $db - > loadObjectList();

function nameComparator($a, $b) {
    return strcmp(strtoupper($a->name), strtoupper($b->name));
}

usort($players, "nameComparator");

Array_multisort不按名称排序
