在条件检查中从xml获取值

我遇到了一个问题

<?php
$movie_name = 'Dabangg';
$url = sprintf(
    'http://api.themoviedb.org/2.1/Movie.search/en/xml/mapi/%s',
    rawurlencode(trim($movie_name))
);
$xml = simplexml_load_file($url);
if (!$xml) 
{
    throw new RuntimeException(sprintf("Failed to open XML from URL '%s'.", $url));
}
$movies = $xml->movies->movie;
foreach ($movies as $movie) 
{
    $movie_id = $movie->id;
    if ($movie_id && is_int($movie_id)) 
    {
        break;
    }
}
echo $movie_id;

我使用上面的代码来获取movieid。现在我意识到当我搜索一个特定的电影时它会获取两个电影结果

在这个结果中有两个电影id。我想要的Id是147405，但是我只得到了Id 44425。我怎样才能得到另一个电影ID ?

如果我们看到我搜索<name>Dabangg 2</name>位的电影名称，它也发送<name>Dabangg</name>。如何检查名称并从xml中获取id

$movieName = 'Dabangg 2';

$apiKey = '30f44b6ef9472d414e50d2acaa058b60';
$url = sprintf(
    'http://api.themoviedb.org/2.1/Movie.search/en/xml/%s/"%s"',
    $apiKey,
    rawurlencode(trim($movieName))
);

$xml = simplexml_load_file($url);
$movie = $xml->movies->movie;
echo $movieName, ': ', $movie->id; # Dabangg 2: 147405
