php数组导入mysql

Question

$sql_where = ''; $exclude = '30,35,36,122,123,124,125';

if($exclude != '') 
{     
    $exclude_forums = explode(',', $exclude); 
    foreach ($exclude_forums as $id) 
    { 
        if ($id > 0) 
        { 
            $sql_where = ' AND forum_id <> ' . trim($id); 
        } 
    }
} 

$sql = 'SELECT topic_title, forum_id, topic_id, topic_type, topic_last_poster_id, topic_last_poster_name, topic_last_poster_colour, topic_last_post_time
   FROM ' . TOPICS_TABLE . '
   WHERE topic_status <> 2
      AND topic_approved = 1
      ' . $sql_where . '
   ORDER BY topic_time DESC';

上面的代码我用来排除要在 sql 查询中显示的论坛 id。

为什么不行还显示呢？

任何解决方案

您在 =

之前遗漏了点

$sql_where .= ' AND forum_id <> ' . trim($id);
