各位大神，输出数组有这么一段代码：

<?      
$db =&JFactory::getDBO();
$query = "SELECT field_id,item_id,value FROM a68y5_fields_values WHERE field_id='27'";
$db->setQuery($query);
$result = $db->loadObjectList();
print_r($result);
?>  

我们得到以下输出：

Array([0] => stdClass Object([field_id] => 27[item_id] => 57[value] => {"items":[{"caption":"","thumbnail":"media\/acfgallery\/content\/57\/27\/turkue-2_thumb.jpg","image":"media\/acfgallery\/content\/57\/27\/turkue-2.jpg"},{"caption":"","thumbnail":"media\/acfgallery\/content\/57\/27\/cei-tr-17-20_thumb.jpg","image":"media\/acfgallery\/content\/57\/27\/cei-tr-17-20.jpg"},{"caption":"","thumbnail":"media\/acfgallery\/content\/57\/27\/376e2e826ef05422273ec4ce4aeea6a7_thumb.jpg","image":"media\/acfgallery\/content\/57\/27\/376e2e826ef05422273ec4ce4aeea6a7.jpg"},{"caption":"","thumbnail":"media\/acfgallery\/content\/57\/27\/20210408193043834296329o_thumb.jpg","image":"media\/acfgallery\/content\/57\/27\/20210408193043834296329o.jpg"},{"caption":"","thumbnail":"media\/acfgallery\/content\/57\/27\/azura_park_room_1_thumb.jpg","image":"media\/acfgallery\/content\/57\/27\/azura_park_room_1.jpg"}]})[1] => stdClass Object([field_id] => 27[item_id] => 56[value] => {"items":{"0":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/cei-tr-17-20_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/cei-tr-17-20.jpg"},"1":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/turkue-2_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/turkue-2.jpg"},"2":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/376e2e826ef05422273ec4ce4aeea6a7_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/376e2e826ef05422273ec4ce4aeea6a7.jpg"},"3":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/20210408193043834296329o_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/20210408193043834296329o.jpg"},"5":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/azura_park_room_1_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/azura_park_room_1.jpg"},"6":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/27173286512962220648konak-city-towers-in-alanya_13_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/27173286512962220648konak-city-towers-in-alanya_13.jpg"}}}))

如何仅输出 56[value] => I.e. 中包含的内容 需要这个代码：

{"items":{"0":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/cei-tr-17-20_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/cei-tr-17-20.jpg"},"1":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/turkue-2_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/turkue-2.jpg"},"2":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/376e2e826ef05422273ec4ce4aeea6a7_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/376e2e826ef05422273ec4ce4aeea6a7.jpg"},"3":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/20210408193043834296329o_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/20210408193043834296329o.jpg"},"5":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/azura_park_room_1_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/azura_park_room_1.jpg"},"6":{"caption":"","thumbnail":"media\/acfgallery\/content\/56\/27\/27173286512962220648konak-city-towers-in-alanya_13_thumb.jpg","image":"media\/acfgallery\/content\/56\/27\/27173286512962220648konak-city-towers-in-alanya_13.jpg"}}}

谢谢您的帮助！

您需要按顺序将所有 111 替换为数字。如何实施？理想情况下，应该设置数字报告，例如从 3000 开始。谢谢。

像这样的源代码：

<item id="111">
<title>Заголовок</title>
<description>Описание</description>
<images>
<image id="111">фото1</image>
<image id="111">фото2</image>
</images>
</item>
<item id="111">
<title>Заголовок</title>
<description>Описание</description>
<images>
<image id="111">фото1</image>
<image id="111">фото2</image>
</images>
</item>
<item id="111">
<title>Заголовок</title>
<description>Описание</description>
<images>
<image id="111">фото1</image>
<image id="111">фото2</image>
