URL、PHPから取得したJSONにデータを追加

Question

私は結果を得るためにWikipedia Webサービスを使用しています。 PHPで取得したJSONファイルにデータを追加するのが好きです。データを追加する前にJSONファイルをデコードする必要がありますが、データを次の形式で追加する方法は示されていません。

私のPHPコード：？

<?php 

//---------------------Wikipedia Web Service------------------- 
$json_array = array(); 
$answer_data = array(); 

$command_text = ""; 

if(isset($_POST["command"]) && !empty($_POST["command"])){ 
    $command_text = $_POST["command"]; 
} 

//JSON link and get data and then send data back to client 
$url = 'https://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=' . $command_text .'&format=json'; 
$json = file_get_contents($url); 
$json_decode = json_decode($json, true); 



$newer['query']['search'][20] = array("title"=>"OWL Witch", "snippet"=>"One crazy owl!"); 

array_push($json_decode, $newer); 

//----------------OUTPUT JSON----------------- 
//header function converts JSON to objects (no need JSON.parse() javascript function)! 
header("Content-type:application/json"); 
echo json_encode($json_decode);

JSONファイル：

私が追加する方法を、検索タグ（JSON）に私の新しいデータを追加しますPHPを使用して壮大な子供の新しいデータですか？

種類はこれを

Answer 1

代わりについて：

$newer['query']['search'][20] = array("title"=>"OWL Witch", "snippet"=>"One crazy owl!"); 

あなたはちょうどこの操作を行うことができます。

$json_decode['query']['search'][20]['title'] = 'OWL Witch'; 
$json_decode['query']['search'][20]['snippet'] = 'One crazy owl!'; 

あなたは本当にあなたの変数$ json_decodeはしかし、それは非常に混乱だ呼び出すべきではありません

EDIT

私はちょうどあなたのjsonを見て、これはそれを行うための最良の方法ではないかもしれないことを認識しました。

$json_decode['query']['search'][] = array("title"=>"OWL Witch", "snippet"=>"One crazy owl!"); 

この意志：私はあなたが実際に既存の最後に新しいエントリを追加されて何をしたいのか、その後、より良い方法は次のようになります場合は、$json_decode['query']['search'][20]

に固有の情報を追加したいと想定していました配列に現在入っているエントリの数に関係なく、$json_decode['query']['search']配列の次の数値配列キーとして新しいエントリを追加します。
