平常操作数据库获得的资料都是二维阵列：$rows[列数][字段名]
例如，假设要获取文章的资料，资料表叫 Post。常捞出来的结果像这样
[0] => Array
(
[id] => 1
[title] => First article
[content] => aaa
[created] => 2008-05-18 00:00:00
)
[1] => Array
(
[id] => 2
[title] => Second article
[content] => bbb
[created] => 2008-05-18 00:00:00
)
但是 cakephp 会在中间多一层，把资料表名称放进去：
[0] => Array
(
[Post] => Array
(
[id] => 1
[title] => First article
[content] => aaa
[created] => 2008-05-18 00:00:00
)
)
[1] => Array
(
[Post] => Array
(
[id] => 2
[title] => Second article
[content] => bbb
[created] => 2008-05-18 00:00:00
)
)
我知道这个另有用处。但是如果不想要中间多那一层，该如何处理？
$postData = $this->Post->find('all',array(??), array(??));
