多次元配列をjson形式に変換する

Question

JSONについて学び始めました。私は後でjsonエンコードに変換する必要がある静的多次元配列を作成する必要があります。今、私は複数の配列を作成することに混乱します。以下は私が試したコードです。私はこの配列に多くの投稿と作者を置くべきです。しかし、それは単一の投稿と著者だけを印刷しています。私は正確にどこで間違ったのか分かりません。

<?php 
    $data['post']= array(
     'title' => 'This is title', 
     'message' =>'This is message', 
     'datetime' => 'This is date time', 
     'bannerImage' =>'' 
     ); 
    $data['author']= array(
     'authorName' => 'Jason Bourne', 
     'userType' => 'Registered User', 
     'address' => 'New York', 
     'profilePic' => 'Profile picture' 
     ); 
    $data['post']= array(
     'title' => 'This is title1', 
     'message' =>'This is message1', 
     'datetime' => 'This is date time1', 
     'bannerImage' =>'' 
     ); 
    $data['author']= array(
     'authorName' => 'Jason Bourne1', 
     'userType' => 'Registered User1', 
     'address' => 'New York1', 
     'profilePic' => 'Profile picture1' 
     ); 
    $datas = array($data); 
    $rss = (object) array('data'=>$datas); 
    $json = json_encode($rss); 
    echo $json;

あなたはlive demo

<?php 

    $data['post']= array(
     'title' => 'This is title', 
     'message' =>'This is message', 
     'datetime' => 'This is date time', 
     'bannerImage' =>'' 
     ); 
    $data['author']= array(
     'authorName' => 'Jason Bourne', 
     'userType' => 'Registered User', 
     'address' => 'New York', 
     'profilePic' => 'Profile picture' 
     ); 
    $datas[] = $data; 
    $data['post']= array(
     'title' => 'This is title1', 
     'message' =>'This is message1', 
     'datetime' => 'This is date time1', 
     'bannerImage' =>'' 
     ); 
    $data['author']= array(
     'authorName' => 'Jason Bourne1', 
     'userType' => 'Registered User1', 
     'address' => 'New York1', 
     'profilePic' => 'Profile picture1' 
     ); 
    $datas[] = $data; 
    $json = json_encode(array('data'=>$datas)); 
    echo $json;
