I have several db calls in my site with bind_variables that works fine. But, I can find the correct sign for Date in the documentation, for the command:
$query->bind_param("ssi",...);
I don't want to do something like:
$db->query('SELECT item FROM table WHERE something='.$something);
Since this is string manipulation, not binding. (In binding the query is left with the "?" and that makes the queries faster because the DB sees them the same only with different cariables.)
If I wasn't very clear, I want to do the same as this only with a date variable type.
