我有问题

<?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;

我用上面的代码来感染 movieid 。现在我意识到，当我搜索特定电影时，它会获取两部电影结果

此结果中有两个电影 ID。我想要的 ID 是 147405，但我只得到 ID 44425。我怎样才能获得另一个电影 ID。

如果我们看到我搜索的电影名称，<name>Dabangg 2</name>它<name>Dabangg</name>也会发送 . 如何检查名称并从 xml 中获取该 ID。

如果您想搜索确切的术语，例如

$movieName = 'Dabangg 2';

您需要将其用双引号括起来：

$apiKey = '30f44b6ef9472d414e50d2acaa058b60';

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

这将允许您立即获得您正在寻找的 ID：

$xml = simplexml_load_file($url);
$movie = $xml->movies->movie;

echo $movieName, ': ', $movie->id; # Dabangg 2: 147405

break结束当前的执行while。然后不要使用它，因为在第一次找到匹配后，它会结束while循环
