So I have a link that returns a jSON object, and I need to have it decoded and put into variables in PHP.
所以我有一个返回一个 JSON 对象的链接，我需要将它解码并放入 PHP 中的变量中。
URL
网址
api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1
This is the object that it returns
这是它返回的对象

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.

So how can I extract the jSON object and put it in to correct variables in PHP, that I can later use?
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？
Variables like: $username, $user_id, $message, $title, $discussionState, and so on.
变量，如：$username，$user_id，$message，$title，$discussionState，等。
I just need to know how I can retrieve the jSON object, then extract the data into variables in PHP.
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。
I am now able to get the PHP array, but I am having some troubles calling the correct values. Here is the array.
我现在能够获取 PHP 数组，但是我在调用正确值时遇到了一些麻烦。这是数组。
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] => ) ) ) ) ) )
自从我们开始将 phanime 论坛与主站点集成以来，已经有一段时间了。我们现在已经完成了与phanime 论坛和主站点的集成。您将不再注意到有两个平台在运行 phanime，而是只有一个。我们的下一步是为论坛设置主题，使其看起来像主站点！[ip_id] => 268 [message_state] => 可见 [attach_count] => 0 [position] => 0 [likes] => 0 [like_users] => a:0:{} [warning_id] => 0 [warning_message] => ) ) ) ) ) )
Now lets say this array was named $arraythen to get the first element's value "[count]" can't I just say the following: print $array["[count]"]<-- this returns an error.
现在假设这个数组被命名$array为获取第一个元素的值“[count]”，我不能只说以下内容：print $array["[count]"]<-- 这将返回一个错误。
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?
具有作为数组本身的值的[threads]元素呢，也就是元素。我如何获得，也许是[thread_id]元素的价值？

I think this one will answer your question :P

Using cURL
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));
Using file_get_contents
$result = file_get_contents($url);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
Accessing
访问
$array["threads"][13/* thread id */]["title"/* thread key */]
And
和
$array["threads"][13/* thread id */]["content"/* thread key */]["content"][23/* post id */]["message" /* content key */];

to get the object you do not need to use cURL (you are loading another dll into memory and have another dependency, unless you really need curl I'd stick with built in php functions), you can use one simple php file_get_contents(url) function: http://il1.php.net/manual/en/function.file-get-contents.php
要获取不需要使用 cURL 的对象（您正在将另一个 dll 加载到内存中并具有另一个依赖项，除非您确实需要 curl 我坚持使用内置的 php 函数），您可以使用一个简单的 php file_get_contents(url)功能：http: //il1.php.net/manual/en/function.file-get-contents.php
$unparsed_json = file_get_contents("api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1");
$json_object = json_decode($unparsed_json);
then json_decode() parses JSON into a PHP object, or an array if you pass trueto the second parameter.
http://php.net/manual/en/function.json-decode.php
然后 json_decode() 将 JSON 解析为 PHP 对象，如果传递true给第二个参数，则解析为数组。
http://php.net/manual/en/function.json-decode.php
For example:
例如：
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json)); // Object
var_dump(json_decode($json, true)); // Associative array

You can Use this for Curl:
您可以将其用于 Curl：
function fakeip()
{
return long2ip( mt_rand(0, 65537) * mt_rand(0, 65535) );
}
function getdata($url,$args=false)
{
global $session;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: ".fakeip(),"X-Client-IP: ".fakeip(),"Client-IP: ".fakeip(),"HTTP_X_FORWARDED_FOR: ".fakeip(),"X-Forwarded-For: ".fakeip()));
if($args)
{
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$args);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:8888");
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
}
Then To Read Json:
然后阅读Json：
$result=getdata("https://example.com");
Then :
然后 ：
///Deocde Json
$data = json_decode($result,true);
///Count
$total=count($data);
$Str='<h1>Total : '.$total.'';
echo $Str;
//You Can Also Make In Table:
foreach ($data as $key => $value)
{
echo ' <td><font face="calibri"color="red">'.$value[type].' </font></td><td><font face="calibri"color="blue">'.$value[category].' </font></td><td><font face="calibri"color="green">'.$value[amount].' </font></tr><tr>';
}
echo "</tr></table>";
}
You Can Also Use This:
你也可以使用这个：
echo '<p>Name : '.$data['result']['name'].'</p>
<img src="'.$data['result']['pic'].'"><br>';
Hope this helped.
希望这有帮助。

Use this function: http://br.php.net/json_decodeThis will automatically create PHP arrays.
使用这个函数：http: //br.php.net/json_decode这将自动创建 PHP 数组。

You can use this:
你可以使用这个：

$resultado = curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info["url"]);
