通过Echo PHP找到Deezer API艺术品

Question

我在论坛上找到了该代码PHP，我试图适应我的意图，在此链接中，有一个JSON，他们在其中有有关我们搜索的艺术家的信息。但是我只想提取此功能cover_xl

"cover_xl":"https://cdns-images.dzcdn.net/images/cover/1c7a7c081a1e7787321f81a889e9f7b8/1000x1000-000000-80-0-0.jpg"

我一直在尝试许多方面，但是没有结果，所以我来寻求您的帮助。我还留下代码尝试帮助解决方案。

<?php 
    $query = 'https://api.deezer.com/2.0/search?q=sam smith'; 
    $file = file_get_contents($query); 
    $parsedFile = json_decode($file); 
    $albumart = $parsedFile->data[0]->artist->picture[cover_xl]; 
?>

Answer 1

使用以下代码我做了您想要的：

<?php
$url = 'https://api.deezer.com/2.0/search?q=sam%20smith';
$jsonStr = file_get_contents($url);
$jsonArr = json_decode($jsonStr, true);
$coverXlCollection = array();
foreach ($jsonArr['data'] as $row) {
    $coverXlCollection[] = $row['album']['cover_xl'];
}
echo '<pre>'.print_r($coverXlCollection, true).'</pre>';
?>

的结果为：

Array

我对您的代码进行了一些修改，然后将json_decode()函数与第二个参数true进行了。在这种情况下，您将结果作为数组而不是对象。

欢呼。
