我从网站获得了json回复，
然后将其转换为json解码文件，我的代码是
$author = $_POST['author_name'];
$author_name = str_replace(' ', '+', $author);
$term = $_POST['term'];
$term_search = str_replace(' ', '+', $term);
$country = $_POST['country'];
$entity = 'ebook';
$search_url = "https://itunes.apple.com/searchterm=".$term_search."&entity=".$entity."&country=".$country;
$data = file_get_contents($search_url);
$josn_decoded = json_decode($data, true);
$file_name = "searched_book.csv";
$fp = fopen($file_name, 'w');
foreach($josn_decoded['results'] as $search_result){
fputcsv($fp, $search_result);
}
fclose($fp);
echo "<pre>"; print_r($josn_decoded)的回复就像
<pre>Array

当我把它写入csv文件时，我得到以下错误
第29行D：\ wamp \ www \ search_book \ search_code.php中的数组到字符串转换
请指导我..我是这个新手

fputcsv只接受一维数组，而不是多维数组。您必须将genres，genreIds，artistIds等转换为字符串。也许你需要类似implode()方法的东西。
例如：
foreach($josn_decoded['results'] as $search_result) {
if (is_array($search_result)) {
$search_result = implode('|', $search_result);
}
fputcsv($fp, $search_result);
}
所以在csv中，您的genres列就像Cookbooks, Food & Wine|Books|Business & Personal Finance。

试试这个：）
<?php
$json_str = "{'aintlist':[4,3,2,1], 'astringlist':['str1','str2']}";
$json_obj = json_decode ($json_str);
$fp = fopen('file.csv', 'w');
foreach ($json_obj as $fields)
{
fputcsv($fp, $fields);
}
fclose($fp);
?>
