file_get_contentsを使用したJSONからPHPへの配列

Question

雑誌のAPIを使用して以下のjsonコンテンツを取得しようとしています。 jsonの出力は次のようになります。私は以下のJSONをphp配列に変換したい。

{ 
"bpath": "http://www.sampledomain.com/", 
"clist": [ 
    { 
     "cid": "11", 
     "display_type": "grid", 
     "ctitle": "abc", 
     "acount": "71", 
     "alist": [ 
      { 
       "aid": "6865", 
       "adate": "2 Hours ago", 
       "atitle": "test", 
       "adesc": "test desc", 
       "aimg": "", 
       "aurl": "?nid=6865", 
       "weburl": "news.php?nid=6865", 
       "cmtcount": "0" 
      }, 

      { 
       "aid": "6857", 
       "adate": "20 Hours ago", 
       "atitle": "test1", 
     "adesc": "test desc1", 
     "aimg": "", 
       "aurl": "?nid=6857", 
       "weburl": "news.php?nid=6857", 
       "cmtcount": "0" 
      } 
     ] 
    }, 
    { 
     "cid": "1", 
     "display_type": "grid", 
     "ctitle": "test1", 
    "acount": "2354", 
     "alist": [ 
      { 
       "aid": "6851", 
       "adate": "1 Days ago", 
       "atitle": "test123", 
     "adesc": "test123 desc", 
     "aimg": "", 
       "aurl": "?nid=6851", 
       "weburl": "news.php?nid=6851", 
       "cmtcount": "7" 
      }, 
      { 
       "aid": "6847", 
       "adate": "2 Days ago", 
       "atitle": "test12345", 
     "adesc": "test12345 desc", 
     "aimg": "", 
       "aurl": "?nid=6847", 
       "weburl": "news.php?nid=6847", 
       "cmtcount": "7" 
      } 
     ] 
    }, 

] 
} 

私のコードは次のようになります。

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu"; 
$json = file_get_contents($json_url); 
$data = json_decode($json, TRUE); 
echo "<pre>"; 
print_r($data); 
echo "</pre>"; 
?> 

上記のコードは空の配列を返します。 :(それはPHPのオブジェクト配列に上記のJSONに変換することが可能である方法 。 私は無力だ。

おかげ ハーン

Answer 1

あなたが提供するJSONのサンプルが有効ではありません。このJSONバリデータをオンラインでチェックhttp://jsonlint.com/ 。あなたは、あなたが配列に変換するために、このコードを使用することができ、有効なJSONを持っている行に59

一つを余分なコンマを削除する必要が

json_decode（真の$ JSON、）;。

Array 
(
    [bpath] => http://www.sampledomain.com/ 
    [clist] => Array 
     (
      [0] => Array 
       (
        [cid] => 11

Answer 2

JSONは有効な文字列ではありません.Galbraithが上記のとおりです。

ここにその解決策があります。

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu"; 
$json = file_get_contents($json_url); 
$json=str_replace('}, 

]',"} 

]",$json); 
$data = json_decode($json); 

echo "<pre>"; 
print_r($data); 
echo "</pre>"; 
?> 

このコードを使用すると、効果的です。

Answer 3

はJSONオブジェクトが不正な形式であるため、あなたはおそらく、空の配列を取得している「」

<?php 
//file_get_content(url); 
$jsonD = '{ 
    "bpath":"http://www.sampledomain.com/", 
    "clist":[{ 
      "cid":"11", 
      "display_type":"grid", 
      "ctitle":"abc", 
      "acount":"71", 
      "alist":[{ 
        "aid":"6865", 
        "adate":"2 Hours ago", 
        "atitle":"test", 
        "adesc":"test desc", 
        "aimg":"", 
        "aurl":"?nid=6865", 
        "weburl":"news.php?nid=6865", 
        "cmtcount":"0" 
       }, 
       {

$parseJ = json_decode($jsonD,true); 

print_r($parseJ); 
?>
