使用 PHP 从 URL 获取 JSON 对象

问题描述

我有一个以 JSON 格式提供不同响应的 URL。我需要使用 PHP 获取响应并显示 target_url。我用这段代码成功地做到了。

<?PHP
        $content = file_get_contents("https://code.directadvert.ru/show.cgi?adp=5357330&json=22");
        $content = utf8_encode($content);
        $result = json_decode($content,true);
        $url = $new['target_url'];

        foreach($result['news'] as $new) {
            echo $new['target_url'];
        }
?>

但我只得到两个相同答案中的一个。每次我都必须以不同的方式接收它。可能是什么问题？

解决方法

您已经有了 JSON .. 不需要循环.. 只需深入到 URL ..

<?php
    $content = file_get_contents("https://code.directadvert.ru/show.cgi?adp=5357330&json=22");
    $content = utf8_encode($content);
    $result = json_decode($content,true);

    $url = $result['news'][0]['target_url'];
    
    echo $url;

当你 json_decode -- 你的 $result 变成：

Array
(
    [news] => Array
        (
            [0] => Array
                (
