php - 如何从 url 获取数据到数组？

问题描述

我用 php 很糟糕。我不是只为我的私人事情做点什么的程序员。我有这样一个问题，我想从我的 PV 产品中下载数据。数据格式如下。如何分别从 php 中的 url 下载数据，对它们进行分组并将它们发送到数组？预先感谢您的所有帮助。

解决方案

试试这个

<?php 

$json_url = file_get_contents('Your url goes here');
$data = json_decode($json_url,true);

var_dump($data);
// You can print all of your data here to see if it works
foreach ($data as $items) {
    // You can loop trough the data and get it like $items->sid etc
    var_dump($items);
}

?>

您需要使用“ file_get_contents ”获取 URL，而不是使用json_decode对其进行解码

然后用 for each 函数打印出来
