Answer 1

Right off the bat, let me tell you that storing CSV values in a database is almost never a good idea! It demonstrates poor database design and bad data integrity. It'll likely cause issues further down the line and make working with the data later much more difficult.

Anyway, that having been said, if you still wish to do this, you can use implode() to conver the array into a string, that can then be inserted into your MySQL database:

$dbString = implode(',', $ids);

It would be much better to store the blocked users in another link table.
