所以我有一个返回jSON对象的链接，我需要将其解码并放入PHP中的变量中。
api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1
它返回的对象

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.

那么我如何提取jSON对象并将其放入PHP中正确的变量，以便以后使用?
变量:$username、$user_id、$message、$title、$discussionState等。
我只需要知道如何检索jSON对象，然后将数据提取到PHP中的变量。
我现在能够得到PHP数组，但我有一些麻烦调用正确的值。这是数组
Array ([count] => 1 [threads] => Array ([13] => Array ([thread_id])=> 13 [node_id] => 4 [title] =>论坛整合接近完成![reply_count] => 0 [view_count] => 0 [user_id] => 59 [username] =>Faeron [post_date] => 1369257302 [sticky] => 0 [discussion_state] =>Visible [discussion_open] => 1 [discussion_type] => [first_post_id] =>23 [first_post_likes] => 0 [last_post_date] => 1369257302[last_post_id] => 23 [last_post_user_id] => 59 [last_post_username] =>Faeron [prefix_id] => 1 [content] => Array ([count] => 1 [content] =>数组([23]=>数组([post_id] => 23 [thread_id] => 13 [user_id] =>59 [username] => Faeron [post_date] => 1369257302 [message] => It's从我们开始整合ph动漫论坛到现在已经有一段时间了主站点。我们现在已经完成了与ph动漫的集成论坛和主要网站。你将不再注意到有两个运行ph动漫的平台，但不是只有一个。我们的下一步是主题论坛，使其看起来像主要的网站![ip_id] => 268[message_state] => visible [attach_count] => 0 [position] => 0 [likes]=> 0 [like_users] =>: 0: {} [warning_id] => 0 [warning_message ] => ) ) ) ) ) )
现在，假设这个数组被命名为$array，那么为了获得第一个元素的值"[count]"，我不能这样说:print $array["[count]"] <——这将返回一个错误。
如果元素本身有一个值作为数组，也就是[threads]元素呢?我如何获得[thread_id]元素的值?
我想这个可以回答你的问题: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));
使用file_get_contents
$result = file_get_contents($url);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
访问
$array["threads"][13/* thread id */]["title"/* thread key */]
和
$array["threads"][13/* thread id */]["content"/* thread key */]["content"][23/* post id */]["message" /* content key */];
Curl:
function fakeip()
{
return long2ip( mt_rand(0, 65537) * mt_rand(0, 65535) );
}
function getdata($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:
$result=getdata("https://example.com");
:
///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>";
}
你也可以用这个:
echo '<p>Name : '.$data['result']['name'].'</p>
<img src="'.$data['result']['pic'].'"><br>';
希望有帮助。
获取对象，你不需要使用cURL(你正在加载另一个dll到内存中，有另一个依赖，除非你真的需要cURL我坚持内置的php函数)，你可以使用一个简单的php file_get_contents(url)函数: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);
json_decode()将JSON解析为PHP对象，如果将true传递给第二个参数，则解析为数组。http://php.net/manual/en/function.json-decode.php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json)); // Object
var_dump(json_decode($json, true)); // Associative array
也可以使用
$result = curl_exec($ch);
return response()->json(json_decode($result));
使用此函数:http://br.php.net/json_decode这将自动创建PHP数组
你可以这样做:
curl_setopt_array($ch, $options);
$resultado = curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info["url"]);
