INSERT INTO tbl_course_offred (0, 1, 2, 3, 4, 5, 6, 7, 8, user_id) VALUES ('1', '2', '3', '4', '89', '5', '22', '106', '133', '11')

The values between the first parenthesis should be the column names. Not sure where these are coming from, but those columns aren't in your table.

It looks as if you've got a strange schema. You can use bitwise operators and addition to retrieve and store this type of data.

$skills = array_sum($_POST['skill']);

However, your skill[] values would need to be 1,2,4,8,16 etc.

You could then search with bitwise oeprators:

SELECT ... FROM ... WHERE `skills` & 2

Just a thought.
