JSONデータセット構造

Question

json配列にmysqlレコードを作成していますが、jsonデータセットに問題があるようです。 PFBコード： -

JSON出力が来る

： - ：私は代わりに、各レコードに来る、これらは来るべき[]これらのブラケットを意味

[{ 
    "ID": "1", 
    "Coupon_ID": "ABC1", 
    "Campaign_ID": "353", 
    "Campaign_Name": "Test1", 
    "Title": "Test1", 
    "Description": "Test1", 
    "Category": "Test1", 
    "Type": "Coupon", 
    "Type_Value": "1231", 
    "Tracking_URL": "http://abc1.com", 
    "Added_Date": "2016-07-13", 
    "Expiry_Date": "2016-07-28" 
} 
{ 
    "ID": "2", 
    "Coupon_ID": "ABC2", 
    "Campaign_ID": "3532", 
    "Campaign_Name": "Test2", 
    "Title": "Test2", 
    "Description": "Test2", 
    "Category": "Test2",

    "Added_Date": "2016-07-13", 
    "Expiry_Date": "2016-07-28" 
}]

私はこのような何かをしたいです1回だけ。

PHPコード： - あなたが初期化するために/あなたのJSON配列エコーしばらく外に必要

ループ：

$json = array(); 
while(....) { 
    while(....) { 
     //....... 
     array_push($json, $value); 
     //....... 
    } 
} 
echo json_encode($json, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

あなたがループ内で生成されたすべてのデータを取得する場合は、あなただけの変数内のすべてのデータを保存して、スクリプトの最後とループの外まで出力 echo $whatever;が異なるする必要があるかもしれません。あなたが一度で一緒にすべてのデータを取ることが確実であるそのように...あなたを少し変更したとコメントし 次のコードは、それがすべてのより良い

     // CREATE A VARIABLE THAT WOULD HOLD ALL THE DATA (ARRAY GENERATED IN THE LOOP) 
     // INITIALIZE IT TO THE DEFAULT "FAILURE" MESSAGE..."0 Results" 
     // THAT WAY; YOU WOULDN'T NEED ANY else if() CLAUSE... 
     $jsonData  = array("message"=> "0 results"); 

     // Create connection 
     $conn = new mysqli($servername, $username, $password, $dbname);
