の正しい作業PDOサーバーのコピーを入手できますどのように私は多くのlessionと読書に行うPDOに新しいですが、PDOサーバーコードに以下の私のmysqliのコードを変換しようとしています：私は私のコード
すべての変更しようとし<?php

午前"]）私のデータベースに更新されると私はなぜそれが結果を出力しない理由を把握できない新しいpdoステートメントが頼むインナー私は私たちがこの後に大丈夫だと信じています。
私のコードがレコードをデータベースに挿入するのはなぜですか？
エラー報告をオンにすると、 '$ conn = new PDO（...）; 'が開始されていないことがわかります。 – ino
あなたの質問の1つに問題があります： 'used = loading'。 – Progrock
ループして複数の挿入を行っている場合は、準備済みのステートメントを再利用します。 – Progrock
