阅读关联阵列

Question

我有以下数组...从此代码生成。

$aa = new_Arr(); 

print_r($aa); //here is the result... 


    cl_aa Object 
    (
     [data:cl_aa:private] => Array 
      (
       [t_a] => Array 
        (
         [0] => Array 
          (
           [f_c] => LAL 
           [p_r] => RN 
           [id] => 1214125 
           [gender] => m 
          ) 
        ) 

       [t_b] => Array 
        (
        ) 

       [t_l] => Array 
        (
         [0] => Array 
          (
           [p_lev] => 2 
           [p_date] => 
           [p_r] => 
          ) 
        ) 

       [t_r] => Array 
        (
         [0] => Array 
          (
           [I_r] => 19 
          ) 

        ) 

      ) 

     [db:cl_aa:private] => PDOTester Object 
      (
      ) 
    ) 

我尝试它读成这样......

foreach ($aa as $key=>$value) { 
    print_r($key); 
    echo "<h1>". $value['bb']. "</h1>"; 
} 

，但没有结果，我可以看到...

我怎么看了上面的阵列？请帮助？

提供您cl_aa类的一些干将：

public class cl_aa { 

    private $data; 
    private $db; 

    public function getData() { 
     return $this->data; 
    } 
    public function getDb() { 
     return $this->db; 
    } 
} 

，并从外部访问您的数据：

$aa = new_Arr(); // I assume this function returns a cl_aa object. 
print_r($aa->getData()); 
print_r($aa->getDb());
