Try this:

1.The print_r(variable); function is used to print human-readable information about a variable.

2.The var_dump(variable); function is used to display structured information (type and value) about one or more variables.

    }
     else {

    //header("Location:new.php");
        echo "send";
        }
    $conn->close();
?>

Array ( [0] => on [1] => on [2] => on ) this is what printing when i use print_r($_POST['friend']); or var_dump($_POST['friend']) but i want to display the search result of Name,EmailAddress,Qualifiaction — Arun Kumaresh, Dec 28 '15 at 06:44
Than you need put in form also something about this: ``'. And check query `SELECT * FROM form WHERE id in ( :id1, :id2, ...)` to search rows for each id, where `$_POST['friend'][i]` is on. — Nick, Dec 28 '15 at 06:54
