Is mysql_real_escape_string() necessary when using prepared statements?

For this query, is necessary to use mysql_real_escape_string?

Any improvement or the query is fine ?

$consulta = $_REQUEST["term"]."%";

($sql = $db->prepare('select location from location_job where location like ?'));

$sql->bind_param('s', $consulta);
$sql->execute();
$sql->bind_result($location);

$data = array();

while ($sql->fetch()) {
    $data[] = array('label' => $location);
}

The query s开发者_如何学运维peed is important in this case.

No, prepared queries (when used properly) will ensure data cannot change your SQL query and provide safe querying. You are using them properly, but you could make just one little change. Because you are using the '?' placeholder, it is easier to pass params through the execute method.

$sql->execute([$consulta]);

Just be careful if you're outputting that to your page, SQL parameter binding does not mean it will be safe for display within HTML, so run htmlspecialchars() on it as well when outputting.
