php 阅读 kodi/xbmc 电影 nfo 文件

Question

我正在编写一个 php 脚本来解析 kodi 生成/使用的电影 nfo 和电视 nfo 文件。

但是我在获取一些子属性时遇到了问题（不确定这是否是正确的术语。）

到目前为止，我正在使用 simplexml 来读取 nfo 文件并收集数据。

但是我很难获得数据的评级和评级子集。

我无法找出正确的上下文来获得我想要/需要的特定值。

<ratings>
<rating default="false" max="100" name="metacritic">
  <value>46.0</value>
  <votes>0</votes>
</rating>
<rating default="false" max="10" name="themoviedb">
  <value>6.6</value>
  <votes>1175</votes>
</rating>
<rating default="false" max="100" name="tomatometerallcritics">
  <value>56.0</value>
  <votes>36</votes>
</rating>
<rating default="false" max="10" name="tomatometeravgcritics">
  <value>4.5</value>
  <votes>36</votes>
</rating>
<rating default="true" max="10" name="imdb">
  <value>6.6</value>
  <votes>91750</votes>
</rating>
<rating default="false" max="10" name="trakt">
  <value>7.2</value>
  <votes>2629</votes>
</rating>

当我得到结果并解析它们并得到这个数组转储时，我不知道如何获取我想要的特定数据。

Array ( 
    [rating] => Array ( 
        [0] => Array ( 
            [@attributes] => Array ( 
                [default] => false 
                [max] => 10 
                [name] => themoviedb 
            ) 
            [value] => 7.2 
            [votes] => 3716 
        ) 
        [1] => Array ( 
            [@attributes] => Array ( 
                [default] => false 
                [max] => 100 
                [name] => tomatometerallcritics 
            ) 
            [value] => 94.0 
            [votes] => 219 
        ) 
        [2] => Array ( 
            [@attributes] => Array ( 
                [default] => true 
                [max] => 10 
                [name] => imdb 
            ) 
            [value] => 7.3 
            [votes] => 130474 
        ) 
        [3] => Array ( 
            [@attributes] => Array ( 
                [default] => false 
                [max] => 100 
                [name] => metacritic 
            ) 
            [value] => 77.0 
            [votes] => 0 
        ) 
        [4] => Array ( [@attributes] => Array ( [default] => false [max] => 10 [name] => tomatometeravgcritics ) [value] => 7.9 [votes] => 219 ) 
        [5] => Array ( [@attributes] => Array ( [default] => false [max] => 10 [name] => trakt ) [value] => 7.5 [votes] => 8201 ) ) )

这是我在函数中用来抓取和解析 nfo 文件的代码。

    // Read entire file into string
        $xmlfile = file_get_contents($nfo);
          
        // Convert xml string into an object
        $new = simplexml_load_string($xmlfile);
          
        // Convert into json
        $con = json_encode($new);
          
        // Convert into associative array
        $newArr = json_decode($con, true);

我尝试了各种循环，但要么出错，要么什么也没给我。 Array_keys，array_values，我显然没有找到在 nfo 文件中获取这些字段的正确方法。

欢迎任何建议。

[编辑] 所以我想要的输出是这样的： 评级名称，投票。

由于每部电影 nfo 文件中的评分种类各不相同，只是为了能够获得那里的评分，以及他们对所选电影的投票。

[编辑]终于得到了每个评分我想要的所有数据的答案。我不得不对建议的代码进行一些细微的更改，这对我帮助很大！

// loop thru each rating
foreach($movie['rating'] as $a){

    // loop thru each array length
    for($i = 0; $i < count($a); $i++) {

        // get all the properties of the rating
        foreach($a[$i]['@attributes'] as $name => $attrib){

            echo 'Name: ['.$name.']<Br/>';
            echo 'Value: ['.$attrib.']<br/>';
            echo 'Votes: ['.$a[$i]['value'].']<br/';
            echo '<br/>';

        }
    }
}   

这给了我输出：

姓名：[姓名] 值：[imdb] 票数：[6.4]

这是一个更长的列表，但现在我可以获得每个评级及其值/属性。

非常感谢！

$newArr = [
    
        'rating'=> [
                ['@attributes'=>['default'=>'false','max'=>10,'name'=>'The Movie'], 'value'=>1, 'votes'=>5],
                ['@attributes'=>['default'=>'false','max'=>100,'name'=>'The Other Movie'], 'value'=>1, 'votes'=>5]
                ]
];

foreach($newArr['rating'] as $a){
    foreach($a['@attributes'] as $name => $attrib){
        echo 'attributes name = >' . $name . '< and its value is = >' . $attrib . "<\n";
    }
}

结果

attributes name = >default< and its value is = >false<
attributes name = >max< and its value is = >10<
attributes name = >name< and its value is = >The Movie<
attributes name = >default< and its value is = >false<
attributes name = >max< and its value is = >100<
attributes name = >name< and its value is = >The Other Movie<

或者你也可以

$newArr = [
    
        'rating'=> [
                ['@attributes'=>['default'=>'false','max'=>10,'name'=>'The Movie'], 'value'=>1, 'votes'=>5],
                ['@attributes'=>['default'=>'false','max'=>100,'name'=>'The Other Movie'], 'value'=>1, 'votes'=>15]
                ]
];

foreach($newArr['rating'] as $a){
    echo 'max = ' . $a['@attributes']['max'].PHP_EOL;
    echo 'name = ' . $a['@attributes']['name'].PHP_EOL;
    // also easy access to votes and 
    echo 'Votes = ' . $a['votes'] . PHP_EOL;            
}

给予

max = 10
name = The Movie
Votes = 5
max = 100
name = The Other Movie
Votes = 15
