Question

可能重复解析嵌套的JSON：
Nested json to php search listing

我试图解析一些JSON，我现在把一切都在一个页面上分析，但其过多信息放在一个页面上，我希望能够通过列出父对象“教会”来过滤，然后一旦父母被点击，我想孩子（嵌套）对象“轨道”被列出（基本上是为了过滤通过JSON），（想想你的iPod你点击一个艺术家（这是“chur CH“），那么这张专辑（这是”专辑），然后选择曲目（这是在JSON‘轨道’）

让我怎么做一个父对象是JSON解析的一个新的水平有关系吗？

，您可以访问http://ggcc.tv/JSON_Parsers/Music.php，看看有什么我到目前为止

请帮忙，谢谢。

PHP： http://www.godsgypsychristianchurch.net/music.json'; $ content = file_get_contents（$ filepath）; $ json = json_decode（$ content，true）;

$count = 0; 
    foreach ($json['rows'] as $row) { 
     ++$count; 

     echo "<h1>Row: {$count}</h1>"; 
     echo "Album: {$row[doc]['album']}<br />"; 
     echo "Church: {$row[doc]['church']}<br />"; 
     echo "Description: {$row[doc]['des']}<br />"; 
     echo "<img src=\"{$row['doc']['artwork']}\" alt=\"my image \" width=\"250\" /><br /><br />"; 

     $songCount = 0; 
     foreach ($row['doc']['tracks'] as $song) { 
      ++$songCount; 
      echo $song['name'] . ' - '; 

      $songUrl = $row['doc']['baseurl'] . urldecode($song['url']); 
      echo "<a href=\"{$songUrl}\">{$songUrl}</a><br />"; 
     } 
     echo '<br /><br />'; 
    } 

    exit; 
?>

Answer 1

说你想教会链接到他们的音乐，首先将通过循环和教会的名字，摆阵，重复数据删除它们，把它们打印出来，将它们链接像

$churches = array(); 

foreach ($json['rows'] as $row) 
{ 
    if (!in_array($row[doc]['church'], $churches)) 
     $churches[] = $row[doc]['church']; 
} 

foreach ($churches as $church) 
{ 
    print '<a href="getchurchmusic.php?churchname=' . urlencode($church) . '><br />' . htmlentities($church) . '</a>'; } 
} 

然后getchurchmusic.php你现在正在做的，但在教会过滤什么

foreach ($json['rows'] as $row) 
    { 
      if ($_GET['churchname'] == $row[doc]['church']) 
      { 
        /* print out songs or whatever */ 

      } 
    } 

这不是测试，这不是有效的 - 你应该把所有这些数据在数据库，缓存文件等，而不是XSS免费的，这只是粗略的代码给你一个起点
