Question

Please I have to made a small calculus using mysqli and php, and to return a float or a double value, so I’ve tried :

$notes = mysclass_sql::query("SELECT SUM(commentsNote) / COUNT(*) as c
                        FROM comments ")->fetch_object()->c;
return round( $notes , 2) ;

But this returns me a value like this 1,25 and not 1.25 even if I try using str_replace !!

I can’t get out from this, please masters any help ?

Answer 1

You want to use number_format().

$notes = mysclass_sql::query("SELECT SUM(commentsNote) / COUNT(*) as c
                    FROM comments ")->fetch_object()->c;
return(number_format($notes, 2, ".", ""));

fyi, this is the first hit if you google “php comma decimal”.
