Did you forget to include the connection file?

Answer 2

it seems that you didn’t well defined var $conn (with the database configuration) that’s must be the first param of musqli_connect function...

ex:
$conn = mysqli_connect(“localhost”, “admin”, “12345”, “mydatabase”);
msqli_query($conn, “SELECT * FROM table”);
