With the codes below my output that comes after typing "Al" is only "Albania", and it comes duplicated in autocomplete. The result that comes in the chrome console is:

> {"0":"Albania","country_name":"Albania"}

When I run the query in the SQL client the next result is:

mysql> select country_name from countries where country_name like '%Al%'
    -> ;
+--------------------------------+
| country_name                   |
+--------------------------------+
| Albania                        |
| Algeria                        |
| Australia                      |
| Brunei Darussalam              |
| Central African Republic       |
| El Salvador                    |
| Equatorial Guinea              |
| Falkland Islands (Malvinas)    |
| Wallis and Futuna Islands      |
+--------------------------------+

HTML code + JSON:

<form action="" method="post">
    <input type="text" placeholder="Name" id="customerAutocomplte" class="ui-autocomplete-input" autocomplete="off" />
</form>
<script src="jquery-autocomplete/external/jquery/jquery.js" />
<script src="jquery-autocomplete/jquery-ui.min.js"</script>
<script src="jquery-autocomplete/jquery-ui.js"</script>

  $(document).ready(function($){
      $('#customerAutocomplte').autocomplete({
    source:'suggest_name.php',
    minLength:2
      });
  });

PHP code:

<?php
$server = 'localhost';
$user = 'abcdefg';
$password = '12345';
$database = 'Luca';

$mysqli = new MySQLi($server,$user,$password,$database);
/* Connect to database and set charset to UTF-8 */
if($mysqli->connect_error) {
  echo 'Database connection failed...' . 'Error: ' . $mysqli->connect_errno . ' ' . $mysqli->connect_error;
  exit;
} else {
  $mysqli->set_charset('utf8');
}
/* retrieve the search term that autocomplete sends */
$term = trim(strip_tags($_GET['term']));
$data = array();
$data = mysqli_fetch_array($mysqli->query("SELECT country_name FROM countries WHERE country_name LIKE '%$term%' ORDER BY country_name"));
echo json_encode($data);
flush();

$mysqli->close();
?>

Can you help me? =)

How can I develop this layout? Selenium, how to control the execution speed of the test?

This is because you are only getting the first record returned by the query. You have to iterate over the result:

$query = $mysqli->query("SELECT country_name FROM countries WHERE country_name LIKE '%$term%' ORDER BY country_name");

while ($arr = mysqli_fetch_array($query))
{
    $data[] = $arr;
}

echo json_encode($data);
