Get the parameters of the response object

I am new to php. I have the object like this:

object(stdClass)[13]
  public 'GetAttributesResult' => 
    object(stdClass)[14]
      public 'Status' => int 1
      public 'ErrorCode' => int 0
      public 'ErrorMessage' => null
      public 'Result' => 
        object(stdClass)[15]
          public 'SingleAttribute' => 
            array (size=3)
              0 => 
                object(stdClass)[16]
                  public 'L1' => 
                    object(stdClass)[17]
                      public 'int' => int 2
                  public 'L2' => string '52' (length=2)
                  public 'R' => string '3' (length=1)
              1 => 
                object(stdClass)[18]
                  public 'L1' => 
                    object(stdClass)[19]
                      public 'int' => 
                        array (size=2)
                          0 => int 1
                          1 => int 6
                  public 'L2' => string '52' (length=2)
                  public 'R' => string '2' (length=1)
              2 => 
                object(stdClass)[20]
                  public 'L1' => null
                  public 'L2' => string '52' (length=2)
                  public 'R' => string '3' (length=1)
