这是我的第一篇帖子...... 我有一个修改的php文件的问题，但不是来自我。 在菜单项中，我发现此错误： 1054未知列＆＃39;数组＆＃39;在＆＃39; where子句＆＃39; SQL = SELECT * FROM #__content WHERE Array =＆＃39; 4＆＃39; 在另一个菜单项中我发现了这个： 警告：在第113行的/ home / templates / rt_nuance / html / com_tags / tag / default.php中为foreach（）提供的参数无效
这是我的.php文件：

感谢所有人......
答案 0 :(得分：0)
您将返回一个数组，其中需要在查询中为字符串
具体来说，那里应该有一个列名，你得到一个PHP数组。因此，PHP将该数组转换为表示＆＃34; Array＆＃34;在发送给MySQL之前。
