Laravelでrequest->input()を使う時

Requestからデータを得る時

// 推奨
$data = $request->input('data');

// 非推奨
$data = $request->input();
if($data['data']){
  // code...
}

request->input()ドキュメント)を用いる際、上の記述のやり方を用いると良い。
理由は、input()の引数を指定してあげることで、値が代入されていない場合、nullが返されるから。
下の記述だと、dataの値がnullだった場合、undefined variableとなってしまう。
