可能重复：
嵌套 json 到 php 搜索列表

我正在尝试解析一些 JSON，我目前在一个页面上解析了所有内容，但是它的信息太多，无法放在一个页面上，我希望能够通过列出父对象“教堂”来过滤它，然后是父单击我希望列出子（嵌套）对象“曲目”（基本上是通过 JSON 过滤），（想想你的 iPod 你点击一个艺术家（这是“教堂”）然后是一张专辑（其中是“专辑”，然后是曲目（在 json 中是“曲目”）

那么如何使父对象成为解析下一级 JSON 的链接呢？

你可以访问http://ggcc.tv/JSON_Parsers/Music.php看看我到目前为止有什么

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;
?>

假设你想把教堂和他们的音乐联系起来，首先你会循环遍历教堂的名字，把它们排列起来，去重复，打印出来，像这样链接它们

$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>'; }
}

然后在 getchurchmusic.php 中做你现在正在做的事情，但过滤教堂

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

            }
    }

这未经测试，效率不高 - 您应该将所有这些数据放入数据库中，缓存文件等，并且不是 XSS 免费的，这只是粗略的代码，可以为您提供一个起点
