Reddit API - 使用 foreach() 从 Json 中提取信息

Question

我正在尝试使用 PHP 的 foreach() 循环从 Reddit JSON API 中提取标题和 URL。 Here is what the JSON outputs when used in print_r.

这是我目前的代码...

$string_reddit = file_get_contents("http://reddit.com/hot.json");
$json = json_decode($string_reddit, true);

Answer 1

$string_reddit = file_get_contents("http://reddit.com/hot.json");
$json = json_decode($string_reddit, true);  

$children = $json['data']['children'];
foreach ($children as $child){
    $title = $child['data']['title'];
    $url = $child['data']['url'];
}
