私の質問は、これはphpでオブジェクト指向の概念を使用してフォームを作成または作成するための適切な方法ですか？または、さらにオブジェクトを作成するか、変更を加える必要がありますか？

すべてのページにclassperson.phpファイルを含めようとしましたが、次のボタンを使用するとエラーが発生します。

前もって感謝します

まず、「ページ」と呼ばれるものはクライアント側でしか使わないものですが、PHP の場合は単一のスクリプトです。したがって、session_start() を何度も実行しても意味がありません。サーバーにデータを送信するたびに、スクリプトが最初から実行されるためです。また、現在のページの最後に到達しても実行を停止しません。

第二に、セッション変数によって調査ステップを決定するというこのアイデアは、それ自体がちょっと錆びており、適切に実装されていません。私はそれが機能しないことを確信しています（コードを実行していませんが）。セッションに変数を格納することは何も悪いことではありませんが、私のアドバイスは、何らかの方法でロジックを再考することです。たとえば、すべてのフォームで非表示の入力を使用して、ユーザーが調査のどのステップにいるかを確認し、PHP ファイルにすべてのページのケースを含むswitch{}()を含めることができます。

第三に、混乱しないように、ロジックとプレゼンテーションを分離する必要があります。つまり、すべてのフォームに個別のファイルを使用し、ユーザーからデータを受け取り、それを書き留めて（例のように-セッションで）、次に表示するページを選択する別のファイルを使用します。そうすれば、エラーを特定しやすくなり、頭の中でより落ち着くことができます。

また、PHP でのクラスの使用に関する質問については、通常、クラスを一度だけ含める必要があります。たとえば、すべてのロジックを処理するこのファイルに再度含める必要はありません。次に、そのクラスのインスタンスを作成して操作できます。とにかく、あなたは急いでいるように感じます。OOP 手法を始めるのはまだ早いように思えます。一歩一歩進んだほうがよいでしょう。このスクリプトがクラスなしで機能するようにしてください。動作する場合は、ロジックをクラスに抽出します。そうすれば、すべてをよりよく理解できます:)
