上記のコーディングは、パスワードを忘れたシステムのコーディングです。私が試みたが失敗しました。そしてこれがラインNo. 55、私はこの問題に非常に悩まされているので、これを機能させる方法を教えてください。または行のいくつかのテキスト。

$numrows = mysqli_num_rows($query);

これは、クエリが失敗したことを意味します。mysqli_error を使用し、クエリをエコーし​​て問題を確認します。あなたが持っているところならどこでも

$query = mysqli_query($db_conx, $sql);

次を追加する必要があります。

$query = mysqli_query($db_conx, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error(db_conx), E_USER_ERROR);

OOP mysqli への切り替えを検討する必要があります。そうすれば、毎回接続変数を使用する必要がなくなります。
