Answer 1

Make sure you establish a connection to your MySQL database first.

$sql = "insert into yyy (id, twitterid, twitterkullanici, tweetsayisi, takipettigi, takipeden, nerden, bio, profilresmi, ismi) values ('', '$id', '$twk', '$tws', '$tkpettigi', '$tkpeden', '$nerden', '" . mysql_real_escape_string($bio) . "', '$img', '$isim')";

FYI, this could have easily been found with a Google search or using the PHP documention.

Also, you should use this for any strings and/or user submitted data. Not just select fields.
