需要将数据格式话成如下格式:

Array(
  'a' => Array(
    'c' => 'c',
    'd' => Array(
      'e' => 'e',
      'f' => Array(
        'g' => 'g'
        'h' => Array(
          'i' => Array(
            'l' => 'l',
            'm' => 'm'
          ),
          'j' => 'j'
        ),
      )
    )
  ),
  'b' => 'b'
)
