PHP-从数组输出特定内容

如何在此数组中依次输出[Comment][title]s

Array
(  
    [User] => Array
        (
            [id] => 121
            [name] => Gwoo the Kungwoo
            [created] => 2007-05-01 10:31:01
        )
    [Comment] => Array
        (
            [0] => Array
                (
                    [id] => 123
                    [user_id] => 121
                    [title] => On Gwoo the Kungwoo
                    [body] => The Kungwooness is not so Gwooish
                    [created] => 2006-05-01 10:31:01
                )
            [1] => Array
                (
                    [id] => 123
                    [user_id] => 121
                    [title] => More on Gwoo
                    [body] => But what of the ‘Nut?
                    [created] => 2006-05-01 10:41:01
                )
        )
)

如果

$foo

是数组，请执行以下操作：

foreach ($foo['Comment'] as $comment) {
    echo $comment['title'];
}

如果

$foo

foreach ($foo['Comment'] as $comment) {
    echo $comment['title'];
}

那不行，a）应该是a]

foreach ($foo['Comment'] as $comment) {
  echo $comment['title'];
}

在模板中尝试使用此选项，设计师更喜欢此选项：

foreach($foo['Comment'] as $comment):
      echo $comment['title'];
endforeach;

foreach ($foo['Comment'] as $comment) {

有可能吗？看起来是object.cakephp的借口之一？看起来像是一个物体的借口。
