Question

There is probably a simple solution to this question, but if i have the function below and $events contains an unknown number of integers, how would I use the $events variable in a query like this?

function remove_events($events)
{
    $sql = "delete from events where event_id in $events";
    $query = $this->db->query($sql);
}

Answer 1

if $event is a single value then you must use

$sql = "delete from events where event_id = $events";

Or if it is an array

$sql = "delete from events where event_id in (".implode(',', $events).") ";
