更正:
1)您的code
属性没有任何价值。
至少应为空白(""
)。
这被视为错误,您的JSON格式不正确。
2)正确
foreach($json['songs'] as $song){
要:
foreach($json['response']['songs'] as $song){

循环时使用$json['response']['songs']
$jsondata = file_get_contents("hotsongs.json");
$json = json_decode($jsondata, true);
$output = "<ul>";
foreach($json['response']['songs'] as $song){
$output .= "<h4>".$song['name']."</h4>";
$output .= "<h4>".$song['title']."</h4>";
}
$output .= "</ul>";
print_r($output);
