I need some help managing dynamic SQL statements. Depending on what HTML form options have been chosen, I append elements to a SQL statement: 
   if ($time) {
      $sql .= 'AND time = ? ';
   }
   if ($date) {
      $sql .= 'AND date = ? ';
   }

The problem comes when I go to execute the statement. It's difficult for me to determine which arguments to pass to execute() (the variables for the placeholders in the SQL statement). Is there a philosophy, recommended approach, or module that can help with this? Otherwise, I end up with large if statements calling variations of execute()
