PHP的SimpleXML範圍

這是用我的第一次XML文檔。我想要做的是從Spotify搜索中提取一些信息。例如此頁：Spotify Results PHP的SimpleXML範圍

我不是作用域的好，我知道，到目前爲止一切都已經從教程。

我想最終的結果看起來像什麼是財產以後這樣的：

(Album Name) - (Artist Name) (year) 

(track number) - (Track Name) - (length) 
(track number) - (Track Name) - (length) 
(track number) - (Track Name) - (length) 
...

這裏是我到目前爲止的代碼。

<?php 
function print_r2($val){ 
     echo '<pre>'; 
     print_r($val); 
     echo '</pre>'; 
} 

$URL = "http://ws.spotify.com/lookup/1/?uri=spotify:album:77Tgq2oSMvgP4Y9pBVKRJa&extras=trackdetail"; 

$xml = simplexml_load_file($URL) 
    or die("Error: Cannot create object"); 

//print_r2($xml); 

foreach($xml->children() as $album){ 
    echo($album->name); 
    echo($album->artist->name); 
    echo($album->released); 

    foreach($album->children() as $track => $data){ 
     echo $data->{'track-number'}; 
     echo(" - "); 
     echo $data->name; 
     echo(" - "); 
     echo $data->length; 
     echo "<br />"; 
    } 
} 

?>

說我遇到的問題是藝術家的名字和年份沒有顯示，而且它把更多的「 - 」，那麼需要有。（猜它是與兒童（），但不輸出任何數據。）

另外，我在想，我保存到一個數組和處理這些信息的數據到一個SQL數據庫。如果你知道一個更好的寫入陣列的方法，那將是非常棒的。（一舉兩得）。

一個超級簡單的方法來解析XML在可行的數組，像這樣：

<?php 
$xml = file_get_contents('http://ws.spotify.com/lookup/1/?uri=spotify:album:77Tgq2oSMvgP4Y9pBVKRJa&extras=trackdetail'); 

//Type cast XML into Array 
$a = json_decode(json_encode((array) simplexml_load_string($xml)),1); 

//See the full array 
//print_r($a); 

echo $a['name'].' - '.$a['artist']['name'].' - '.$a['released'].'<br />'.PHP_EOL; 

foreach($a['tracks']['track'] as $track){ 
    echo $track['track-number'].' - '.$track['name'].' - '.secondsToTime($track['length']).'<br />'.PHP_EOL; 
}

*/ 

function secondsToTime($seconds){ 
    // minutes 
    $divisor_for_minutes = $seconds % (60 * 60); 
    $minutes = floor($divisor_for_minutes/60); 

    // seconds 
    $divisor_for_seconds = $divisor_for_minutes % 60; 
    $seconds = ceil($divisor_for_seconds); 

    // return the final song len string 
    return $minutes."m".$seconds."s"; 
} 
?>

非常感謝！這真的有幫助。當我在等待答覆我的時候發揮各地與此呼應想出了（gmdate（「H：I：S」輪（floatval（$數據 - >長度））））;但我會在稍後的日期保存該功能，我相信我會在某個時候需要它。 – Throdne

根節點是「專輯」。你應該參考$root->children()，當你應該把根節點當成一個專輯對象。

$url = "http://ws.spotify.com/lookup/1/?uri=spotify:album:77Tgq2oSMvgP4Y9pBVKRJa&extras=trackdetail"; 

$album = simplexml_load_file($url) 
    or die("Error: Cannot create object"); 

echo("name: " . $album->name . "\n"); 
echo("artist: " . $album->artist->name . "\n"); 
echo("released: " . $album->released . "\n"); 
echo "Tracks:\n" ; 
foreach($album->tracks->children() as $track){ 
    echo " " . $track->{'track-number'} . 
     " - " . 
      $track->name . 
      " - " . 
      $track->length . 
      "<br />\n"; 
}

輸出：

真棒，真的幫助我理解與作用域方式你寫你的foreach和以上。 – Throdne

像這樣的事情可能會爲你工作：

<?php 
$url = "http://ws.spotify.com/lookup/1/?uri=spotify:album:77Tgq2oSMvgP4Y9pBVKRJa&extras=trackdetail"; 
$xml = new SimpleXMLElement(file_get_contents($url)); 

$album = array(
    'name' => (string) $xml->name, 
    'artist' => (string) $xml->artist->name, 
    'released' => (string) $xml->released, 
    'tracks' => array() 
); 

foreach ($xml->tracks->track as $track) { 
    $album['tracks'][] = array(
     'number' => (string) $track->{'track-number'}, 
     'name' => (string) $track->name, 
     'length' => (string) $track->length 
    ); 
} 

print_r($album);

謝謝。我正在考慮與二維數組一起去，但不知道如何正確地做到這一點。可能會玩弄勞倫斯和你的代碼，看看什麼對我的應用程序最好。 – Throdne
