この次の方法を使用してPHPでデコードした後、私はJSON形式の変数を参照することができることを知って

Question

こんにちはPHPでJSONから@で変数の開始を参照してください。 json。 どのようにその変数を参照しますか？ $data->form->@nameが機能せず、$data->form['@name']も機能しません。ここ

私のJSONファイルである：（私は@nameをしたい）

あり

Answer 1

あなたが行く：

$a = ['@name' => 'test']; 
$json = json_encode($a); 
$o = json_decode($json); 

echo $o->{'@name'}; // outputs "test" 

Answer 2

解決策はこれを使用することです。

$data->form->{'@name'}
