最后是消息
[ATTACH=full]4143[/ATTACH]
We've completely restructured ShadyCraft, and today will be the launch of the ShadyCraft beta.
Current Features
[LIST]
[*]Towns
[*]Nations
[*]All out wars
[*]A live update map
[*]No White-list
[*]Earn Money
[*]Griefing allowed where possible
[/LIST]
These are just some features which have a lot more things behind them. For instance, there is town and nation upkeep, tax, kingdoms, mayors, and kings.
We really wanted to have the server self-governed and this is why griefing and PvP are allowed where ever they are possible. All towns and nations cannot be griefed by other members. You can create a town and buy plots for it and expand the town as you wish.

那么如何提取 json 对象并将其放入 PHP 中的正确变量中，以便以后使用?
So how can I extract the jSON object and put it in to correct variables in PHP, that I can later use?
变量如:$username、$user_id、$message、$title、$讨论状态，等等.
Variables like: $username, $user_id, $message, $title, $discussionState, and so on.
我只需要知道如何检索 json 对象，然后将数据提取到 PHP 中的变量中.
我现在可以获取 PHP 数组，但是我在调用正确值时遇到了一些麻烦.这是数组.
I am now able to get the PHP array, but I am having some troubles calling the correct values. Here is the array.
Array ( [count] => 1 [threads] => Array ( [13] => Array ( [thread_id]=> 13 [node_id] => 4 [title] => 论坛整合即将完成！[reply_count] => 0 [view_count] => 0 [user_id] => 59 [用户名] =>Faeron [post_date] => 1369257302 [sticky] => 0 [discussion_state] =>可见 [discussion_open] => 1 [discussion_type] => [first_post_id] =>23 [first_post_likes] => 0 [last_post_date] => 1369257302[last_post_id] => 23 [last_post_user_id] => 59 [last_post_username] =>Faeron [prefix_id] => 1 [content] => Array ( [count] => 1 [content] =>数组 ( [23] => 数组 ( [post_id] => 23 [thread_id] => 13 [user_id] =>59 [用户名] => Faeron [post_date] => 1369257302 [message] => 这是自从我们开始将 phanime 论坛与主要站点.我们现在已经完成了与phanime的整合论坛和主站点.你不会再注意到有两个运行 phanime 的平台，但只有一个.我们的下一步是主题论坛，使其看起来像主站点！[ip_id] => 268[message_state] => 可见 [attach_count] => 0 [位置] => 0 [喜欢]=> 0 [like_users] => a:0:{} [warning_id] => 0 [warning_message] => ) ) ) ) ) )
Array ( [count] => 1 [threads] => Array ( [13] => Array ( [thread_id] => 13 [node_id] => 4 [title] => Forum Integration nearly complete! [reply_count] => 0 [view_count] => 0 [user_id] => 59 [username] => Faeron [post_date] => 1369257302 [sticky] => 0 [discussion_state] => visible [discussion_open] => 1 [discussion_type] => [first_post_id] => 23 [first_post_likes] => 0 [last_post_date] => 1369257302 [last_post_id] => 23 [last_post_user_id] => 59 [last_post_username] => Faeron [prefix_id] => 1 [content] => Array ( [count] => 1 [content] => Array ( [23] => Array ( [post_id] => 23 [thread_id] => 13 [user_id] => 59 [username] => Faeron [post_date] => 1369257302 [message] => It's been quite a while since we began to integrate the phanime Forums with the main site. We have now finished the integration with the phanime Forums and the main site. You will no longer notice that there are two platforms running phanime, but instead only one. Our next step is to theme the forums to make it look like the main site! [ip_id] => 268 [message_state] => visible [attach_count] => 0 [position] => 0 [likes] => 0 [like_users] => a:0:{} [warning_id] => 0 [warning_message] => ) ) ) ) ) )
现在假设这个数组被命名为 $array 然后为了得到第一个元素的值 "[count]" 我不能只说以下: print $array["[count]"] <-- 这会返回一个错误.
Now lets say this array was named $array then to get the first element's value "[count]" can't I just say the following: print $array["[count]"] <-- this returns an error.
具有作为数组本身的值的元素呢，它是 [threads] 元素.我如何获得，也许是 [thread_id] 元素的值?
What about the element that has a value as an array itself, which is the [threads] element. How do I get, perhaps the [thread_id] element's value?
推荐答案
我想这个会回答你的问题 :P
I think this one will answer your question :P
$url="https://.../api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1";
使用cURL
// Initiate curl
$ch = curl_init();
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
$result = file_get_contents($url);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
访问
$array["threads"][13/* thread id */]["title"/* thread key */]
和
$array["threads"][13/* thread id */]["content"/* thread key */]["content"][23/* post id */]["message" /* content key */];
