fputcsv只接受一维数组，不接受多维数组。您必须将
流派流派艺术类内爆（）的方法
例如：
因此，在csv中，您的genres
列类似于Cookbooks，Food&Wine | Books | Business&Personal Finance
，这不起作用，因为我的回答是复杂的，而且只是简单的json数组示例。
foreach($josn_decoded['results'] as $search_result) {
if (is_array($search_result)) {
$search_result = implode('|', $search_result);
}
fputcsv($fp, $search_result);
}
