如何删除findall of cakephp中的索引

Question

我有以下代码：

Array
 (
   Array
     (
        [ShowFare] => Array
            (
                [id] => 21
                [press_release_id] => 14
                [category] => 0
                [title] => pr
                [image_name] => 1486719733.jpg
                [crop_image] => 1486719729.jpg
                [is_default] => 0
                [is_active] => 0
                [created] => 2017-02-10 09:42:13
                [created_by] => 0
                [modified] => 2017-02-10 09:42:13
                [modified_by] => 0
                [deleted] => 0000-00-00 00:00:00
                [deleted_by] => 0
            )

        [PressRelease] => Array
            (
                [id] => 
                [title] => 
            )

    )

Array
    (
        [ShowFare] => Array
            (
                [id] => 22
                [press_release_id] => 7
                [category] => 0
                [title] => abcd
                [image_name] => 1486721484.jpg
                [crop_image] => 1486721481.jpg
                [is_default] => 0
                [is_active] => 0
                [created] => 2017-02-10 10:11:24
                [created_by] => 0
                [modified] => 2017-02-10 10:11:24
                [modified_by] => 0
                [deleted] => 0000-00-00 00:00:00
                [deleted_by] => 0
            )

        [PressRelease] => Array
            (
                [id] => 7
                [title] => ht48 hours, 04 March 2016
            )

      )

  )

我想要以下格式的上述结果：

template <typename F>
class FunctorVisitor : public Visitor
{
public:
    explicit FunctorVisitor (F& f) : f(f) {}

    virtual void visit(Node& n) override { f(n);}
    virtual void visit(ANode& n) override { f(n);}
    virtual void visit(BNode& n) override { f(n);}
    virtual void visit(CNode& n) override { f(n);}
    virtual void visit(SubBNode& n) override { f(n);}
private:
    F& f;
};


class CountVisitor
{
public:
    void operator() (const Node& n) const {
        cout << __PRETTY_FUNCTION__ << "\t\tDefault" << endl;
    }
    void operator() (const BNode& n) {
        count++;
        cout << __PRETTY_FUNCTION__ << "\t\tSPECIAL" << endl;
    }

    int count = 0;
    void print() const {
        cout << "CountVisitor Found Bs: "<< count << endl;
    }
};

这可能吗？
