Question

I have a list of items need to be passed which should be deleted. How can I do this in PHP?

$query = "DELETE from members WHERE member_id ='$chan[2]' ";

$chan[2] holds multiple values, but deletes only one.

Answer 1

$chan[2] refers to one element in the $chan array. So, I think you mean that $chan has multiple values.

Try this:

$query = "DELETE FROM members WHERE member_id IN (" . implode(", ", $chan) . ");";
