JSONを解析して特定の値を取得します。

Question 1

まず、jsonが無効です。コンマで区切られた複数の有効なjsonオブジェクトがあります。したがって、各オブジェクトを別々のjson文字列として扱うか、各オブジェクトを外部オブジェクトのキーとしてインストールする必要があります。ここでは、jsonを取得し、キー、、aにb各オブジェクトをインストールしますc。

jsonをコピーして貼り付けてエラーを確認できます。http://jsonlint.com/

これでjsonは次のようになります。

PHPがインストールされている場合は、次のことができます。

文書：parse.php

<?php

$json = file_get_contents('data.json');

$data_obj = json_decode($json);

/* var_dump($data_obj); */

foreach ( $data_obj as $key => $value ) {
    echo $data_obj->{$key}->household_name . PHP_EOL;
    echo $data_obj->{$key}->card_number . PHP_EOL;
}

コマンドラインからPHPスクリプトを実行すると、検索したいキーが出力されます。

php parse.php

出力：

38BA1234
2132312312333344
2134A213
3424567891123242
08A00598
212323311232A213

これにより、通常のgrep、sedコマンドなどを使用できます。
