PHP mySQL votes this month? -


so have voting system. everytime votes, adds new row column called 'votes' details + date, time.

in admin panel, want add feature how many votes have gained month.

how can this?

maybe select rows date not lower curdate() + 30 days, , if yes, delete them ad count how many rows have?

    public function votesthismonth()     {         $this->query = $this->pdo->prepare("select * votes date<date_sub(curdate(), interval 30 day)");         $result = $this->query->execute();          return $result;     }

no need delete anything. mysql can handle lot of data quite easily. @ job have half billion rows in tables.

in query below change year , month current month want query.

select     count(*) num_votes     tablename     year(datecol) = year(current_date) , month(datecol) = month(current_date)
