谁将数组存储在codeigniter中的[{}]内的数据库中

Question

我想使用codeigniter在[{}]大括号内的数据库中存储一个数组。现在，当我将数据存储在数组中时，这些存储就像{}一样。我使用了以下代码：

$addresses = array();
foreach ($langs as $lang=>$long_name)
{ 
  $addresses[$lang] = $this->input->post('address_'.$lang);
  $meta_search_text .= $titles[$lang].' ';
  $meta_search_text .= $addresses[$lang].' ';
}                   

$data['address'] = json_encode($addresses); //store data in address column

输出：

{"en":"pune","es":"","ru":"","ar":"","de":"","fr":"","it":"","pt":"","tr":"","hi":"","bn":""}

我希望它像：

[{"en":"pune","es":"","ru":"","ar":"","de":"","fr":"","it":"","pt":"","tr":"","hi":"","bn":""}]
