Answer 1

Do you really need to use LIKE here? 1 and 2 are so common I don't think it is what you want.

Assuming that is not what you really want, just use IN() . Much simpler.

// Create comma separated list of IDs
$ids = implode(',', $id);
// Use IN() in our WHERE clause
$sql="SELECT * FROM `table` j INNER JOIN `table2` rj ON j.eid = rj.eid WHERE rj.applyto IN($ids);

Answer 2

You just need to implode your ids with comma separated and use FIND_IN_SET for this like:

$ids = implode(',', $id_array);
$sql="SELECT * FROM `table` j INNER JOIN `table2` rj ON j.eid = rj.eid WHERE FIND_IN_SET(rj.applyto, $ids)";

Try this!
