Bagaimana cara menggunakan cURL untuk mendapatkan data jSON dan memecahkan kode data?

Jadi saya memiliki tautan yang mengembalikan objek jSON, dan saya harus membuatnya diterjemahkan dan dimasukkan ke dalam variabel di PHP.

URL

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

Ini adalah objek yang dikembalikannya

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.

Jadi bagaimana cara mengekstrak objek jSON dan memasukkannya ke variabel yang benar di PHP, yang nantinya dapat saya gunakan?

Variabel seperti: $username, $user_id, $message, $title, $discussionState, dan sebagainya.

Saya hanya perlu tahu bagaimana saya bisa mengambil objek jSON, lalu mengekstrak datanya menjadi variabel di PHP.

Saya sekarang bisa mendapatkan array PHP, tetapi saya mengalami beberapa masalah dalam memanggil nilai yang benar. Ini arraynya.

Sudah cukup lama sejak kami mulai mengintegrasikan Forum phanime dengan situs utama. Kami sekarang telah menyelesaikan integrasi dengan Forum phanime dan situs utama. Anda tidak akan lagi melihat bahwa ada dua platform yang menjalankan phanime, tetapi hanya satu. Langkah selanjutnya adalah memberi tema pada forum agar terlihat seperti situs utama! [ip_id] => 268 [message_state] => terlihat [attachment_count] => 0 [posisi] => 0 [suka] => 0 [like_users] => a: 0: {} [warning_id] => 0 [warning_message] =>))))))

Sekarang katakanlah array ini dinamai $arraymaka untuk mendapatkan nilai elemen pertama "[count]" tidak bisakah saya hanya mengatakan yang berikut: print $array["[count]"] <- ini mengembalikan kesalahan.

Bagaimana dengan elemen yang memiliki nilai sebagai array itu sendiri, yang merupakan [threads]elemen. Bagaimana cara mendapatkan, mungkin nilai [thread_id]elemennya?

Saya rasa yang ini akan menjawab pertanyaan Anda: 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";

Menggunakan 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));

Menggunakan file_get_contents

$result = file_get_contents($url);
// Will dump a beauty json :3
var_dump(json_decode($result, true));

Mengakses

$array["threads"][13/* thread id */]["title"/* thread key */]

Dan

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

untuk mendapatkan objek, Anda tidak perlu menggunakan cURL (Anda memuat dll lain ke dalam memori dan memiliki ketergantungan lain, kecuali jika Anda benar-benar membutuhkan curl, saya akan tetap menggunakan fungsi php bawaan), Anda dapat menggunakan satu file_get_contents (url) php sederhana 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);

lalu json_decode () mem-parsing JSON menjadi objek PHP, atau array jika Anda meneruskan trueke parameter kedua. http://php.net/manual/en/function.json-decode.php

Sebagai contoh:

$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

Anda dapat menggunakan ini untuk 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; 
} 

Kemudian Untuk Membaca Json:

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

Kemudian :

///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>";
           }

Anda Juga Dapat Menggunakan Ini:

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

Semoga ini bisa membantu.

Gunakan fungsi ini: http://br.php.net/json_decode Ini secara otomatis akan membuat array PHP.

Anda juga bisa menggunakan

$result = curl_exec($ch);
return response()->json(json_decode($result));

Anda dapat menggunakan ini:

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