javascript自动完成功能无法处理数据库中的所有信息

This is the first time I post a question here, because usually I can find the answer in the questions asked before, this time thought I can't figure it out on my own, so I am counting on your help.

The thing is I use the jQuery autocomplete widget to get information from my database, with a request to get all the hotels name from a hotel table, I'm sure I get all the hotels, but the autocomplete seems not to work with some of them, for example I have 5 hotels : batchmor, sofitel drive, sofitel bartimela, marselle, Juliana. When I press 'b', batchmor and sofitel bartimela will appear, but when I press 's' neither sofitel driver or sofitel bartimela will appear and I don't know the source of the error.

I drop here the jQuery code I use for calling the external PHP file:

//javascript code 
<head>
  <meta charset="utf-8">
  <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.1/themes/base/minified/jquery-ui.min.css" type="text/css" /> 
   <script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
   <script type="text/javascript" src="http://code.jquery.com/ui/1.10.1/jquery-ui.min.js"></script>
</head>
<body>
    <form>
         <input type="text" id="recherche" />
    </form>
    <script type="text/javascript">
       $('#recherche').autocomplete({
          source : 'cnxtobase.php'
        });
    </script>
</body>

and there is the code that's in the cnxtobase.php file

if(isset($_GET['term'])){
    $array = array();
}

try{
    $conn = new PDO('mysql:host=localhost;dbname=Lodging','root','');
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $stmt = $conn->prepare('SELECT name FROM hotel WHERE name LIKE:term');
    $stmt->execute(array(':term' =>'%'.$_GET['term'].'%'));

    foreach ($stmt->fetchAll() as $value) {
        array_push($array, $value['name']);
    }
}catch(PDOException $e) {
    echo 'ERROR: ' . $e->getMessage();
}
echo json_encode($array);

and my database I have

the database

When I use the autocomplete with the letter 'B' or 'ba' I'll get bachaumont but also sofitel baltimor but when I type 'S' I won't get sofitel baltimor, good to know that I add a hotel named soufitel and when I type 'SO' nothing appear but when I type 'sou' soufitel appears.
