Feching的條件檢查

從XML值我有一個問題Feching的條件檢查

<?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;

上面的代碼我使用的fecth的movieid。現在我意識到，當我搜索一個特定的電影也取得了兩部電影造成

有兩個電影IDS這個結果。我想要的Id是147405，但我只能得到Id 44425.我怎樣才能獲得其他電影ID。

如果我們看到電影名稱，我搜索了<name>Dabangg 2</name>位它也發送<name>Dabangg</name>。我如何檢查名稱並從XML中獲取該ID。

當你把鱈魚例子在網站上的這裏，以表明問題的形式寫下來。例如。如果您實際上遇到XML解析問題，則不需要將數據庫交互代碼放在此處。看到我的示例性編輯。 – hakre 2013-05-05 11:29:03

我收到以下問題：*「Warning：'simplexml_load_file（http://api.themoviedb.org/2.1/Movie.search/en/xml/mapi/Dabangg）'：無法打開流：HTTP請求失敗！HTTP/1.1 401 Unauthorized「* – hakre 2013-05-05 11:33:19

@hakre它的問題我沒有提供該URL的API。我不想在這裏公開展示。但是上面的URL將獲取我上面提供的數據 – Yogus 2013-05-05 11:35:33

如果你想搜索字詞完全一樣

$movieName = 'Dabangg 2';

你需要用它在雙引號不使用它，：

$apiKey = '30f44b6ef9472d414e50d2acaa058b60'; 

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

，這將使你獲得你要找立即ID：

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

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

break結束目前的執行while。然後因爲後首次發現匹配，則結束while循環

我仍然在下面刪除了回聲Dabangg％202 44425 – Yogus 2013-05-05 03:44:59

@Deonia，在'while'循環中移動回顯 – Amir 2013-05-05 03:47:14

我在循環中添加echo，它顯示Dabangg％202 147405 44425.這意味着我得到了兩個Id，但是如何只能選擇147405，可以根據標記 – Yogus 2013-05-05 03:52:44
