Question

我遇到了问题

<?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;

上面的代码我用来修饰movieid。现在我意识到，当我搜索特定的电影时，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，但我只得到了Id 44425.我怎么能得到另一部电影ID。

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

Answer 1

如果您想搜索确切的术语，如

$movieName = 'Dabangg 2';

你需要用双引号括起来：

$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

Answer 2

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

在条件检查中从xml中获取值
