From manual page:

In both examples:

// Not a variable : $continent
$stmt->bind_param("s", $continent);

$continent_array = array('Europe','Africa','Asia','North America');

// Here it is:
foreach($continent_array as $continent)

  $stmt->execute(); // Just executing the same query multiple times
  $result = $stmt->get_result();
  while ($row = $result->fetch_array(MYSQLI_NUM))

No, the code is correct. bind_param takes variables by-reference which means they do not have to exist at the time the method is called. The query will use the values of the variables at the time execute() is called.
