It accepts:

<?php
function get_member($member_id) {
    include("connection.php");

    try {
      $results = $db->prepare(
          "SELECT member_id, email, fullname, level
          FROM members where member_id = ?"
      );
      $results->bindParam(1, $member_id);
      $results->execute();
    } catch (Exception $e) {
      echo "bad query";
    }

    $members = $results->fetchAll();
    return $members;
}

First alteration is to accept a parameter to the method. Then you replace the call to query with a call to prepare, with a sql string that includes a placeholder. You bind the parameter into the placeholder (1 based index), then run execute. (ideally, bind param should have a third parameter specifying the type of value being bound)
