Answer 1

you can do something like:

SET @sql_text = 
   CONCAT (
       "SELECT * FROM `tbl_user` into outfile '/xampp/htdocs/mysite/reports-"
       , DATE_FORMAT( NOW(), '%Y%m%d')
       , ".csv'"
    );

PREPARE s1 FROM @sql_text;
EXECUTE s1;
DROP PREPARE s1;

Answer 2

You should use prepared statements. Build a query string, then execute it.
