如何使用cURL来获取json数据和解码数据?

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variables。

url

api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1 

这是它返回的对象

 { "count": 1, "threads": { "38752": { "thread_id": 38752, "node_id": 4, "title": "The ShadyCraft Beta Launch!", "reply_count": 45, "view_count": 946, "user_id": 2, "username": "Shady", "post_date": 1366956695, "sticky": 0, "discussion_state": "visible", "discussion_open": 1, "discussion_type": "", "first_post_id": 226167, "first_post_likes": 7, "last_post_date": 1369094302, "last_post_id": 228226, "last_post_user_id": 2, "last_post_username": "Shady", "prefix_id": 19, "tinhte_xentag_tags": "a:4:{i:0;s:9:\"minecraft\";i:2;s:4:\"news\";i:3;s:14:\"private server\";i:1;s:10:\"shadycraft\";}", "content": { "count": 1, "content": { "226167": { "post_id": 226167, "thread_id": 38752, "user_id": 2, "username": "Shady", "post_date": 1366956695, "message": "[ATTACH=full]4143[\/ATTACH]\n \nWe've completely restructured ShadyCraft, and today will be the launch of the ShadyCraft beta.\n \nCurrent Features\n[LIST]\n[*]Towns\n[*]Nations\n[*]All out wars\n[*]A live update map\n[*]No White-list\n[*]Earn Money\n[*]Griefing allowed where possible\n[\/LIST]\nThese are just some features which have a lot more things behind them.

我真的只对这个感兴趣

 "title":"The ShadyCraft Beta Launch!", "reply_count:"45, "view_count": 946, "user_id":2, "username":"Shady", "post_date":1366956695, "sticky":0, "discussion_state":"visible", "discussion_open":1, 

最后是消息

那么我怎样才能提取jSON对象,并把它放在正确的PHPvariables,我可以在以后使用?

variables如: $username$user_id$message$title$discussionState等等。

我只需要知道如何检索jSON对象,然后将数据提取到PHP中的variables。

我现在能够得到PHP数组,但是我有一些麻烦调用正确的值。 这是数组。

数组([count] => 1 [threads] => Array([13] => Array([thread_id] => 13 [node_id] => 4 [title] =>论坛集成几乎完成![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] => Array([23] => Array([post_id] => 23 [thread_id] => 13 [user_id] => 59 [username] => Faeron [post_date] => 1369257302 [message] = >我们开始把phanime论坛和主站点整合起来已经有一段时间了,现在我们已经完成了与phanime论坛和主站点的整合,你不再会注意到有两个平台运行phanime,其一,我们下一步是主题论坛,使其看起来像 主站点! [ip_id] => 268 [message_state] => visible [attach_count] => 0 [position] => 0 [likes] => 0 [like_users] => a:0:{warning_id] => 0 [warning_message] =>))))))

现在我们可以说这个数组被命名为$array然后得到第一个元素的值“[count]”我不能说下面的内容: print $array["[count]"] < – 这将返回一个错误。

怎么样的元素有一个值作为数组本身,这是[threads]元素。 我如何得到,也许是[thread_id]元素的值?

我想这个会回答你的问题: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 $ch = curl_init(); // Disable SSL verification curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // 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 */] 

 $array["threads"][13/* thread id */]["content"/* thread key */]["content"][23/* post id */]["message" /* content key */]; 

(你正在加载另一个dll到内存中,并有另一个依赖,除非你真的需要curl我会坚持内置的PHP函数),你可以使用一个简单的PHP file_get_contents(url)function: 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); 

那么json_decode()将JSONparsing为一个PHP对象,如果将true传递给第二个参数,则parsing为一个数组。 http://php.net/manual/en/function.json-decode.php

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 

你可以使用这个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; } 

然后阅读Json:

 $result=getdata("https://site.com"); 

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>"; } 

你也可以使用这个:

 echo '<p>Name : '.$data['result']['name'].'</p> <img src="'.$data['result']['pic'].'"><br>'; 

希望这有助于。

使用这个函数: http : //br.php.net/json_decode这将自动创buildPHP数组。
