1.html_entity_decode函数是 把 HTML 实体转换为字符，引号字符转为引号
2.json_encode 转为数组
$lists = json_decode(html_entity_decode($list));
foreach ($lists as $key => $value) {
   $value = json_decode(json_encode($value), true);
}

1示例：
Array
(
    [0] => stdClass Object
        (
            [title] => 标题:
            [type] => 1
            [images] => 
            [remark] => 333
        )
