How to use php array with sql IN operator?

Question

I have and array with two values and I want to use it with sql IN operator in select query.

Here is the structure of my table

id comp_id
1   2
2   3
         


        

Answer 1

As per @barryhunter 's answer which works only on array that contains integer only:

$sql = "SELECT * from table Where comp_id IN (".implode(',',$arr).")";

I've made some tweaks to make it work for array of strings:

$sql = "SELECT * from table Where comp_id IN ('".implode("','",$arr)."')";
