私はphp MySql予約カレンダーを持っています。これは、予約されているかどうかを日付で表示します。問題は、間違った情報が表示されることです。たとえば、5〜6冊を予約した場合は、5桁目の赤色になり、5桁目に予約されたことを意味します。それは6番目に表示されますが、6時12:00:00までに部屋は無料になります。もう1つの例：私が23-25を予約すると、予約された24,25が表示されますが、問題がどこにあるのか分からない23-25が表示されます。ここでphp mySQL room予約カレンダーが間違った日付を表示している
は、コードは次のとおりです。

私は$ とチェックイン<= '$の_newdate' と '$の_newdate' 考える<=チェックアウト このSQLは正しい結果を取得していません。 –
