感谢您的帮助。 我的打印数组代码： 代码是从instagram过滤数据，但正如您将看到的，我尝试使用var_dump并以此方式过滤我。
<?php
$baseUrl = 'https://www.instagram.com/explore/tags/plebiscito/?__a=1';
$url = $baseUrl;
$count = 0;
$array = array();
while(1) {
$json = json_decode(file_get_contents($url));
var_dump(array_filter($json->tag->media->nodes)); // working
if(!$json->tag->media->page_info->has_next_page) break;
$url = $baseUrl.'&max_id='.$json->tag->media->page_info->end_cursor;
++$count;
}
?>
我想不出任何简单打印代码的想法。
答案 0 :(得分：0)
假设在你的代码中，array_filter($json->tag->media->nodes)返回上面的数组，你可以这样做来获取这个数组并得到'code'值：
<?php
$baseUrl = 'https://www.instagram.com/explore/tags/plebiscito/?__a=1';
$url = $baseUrl;
$count = 0;
$array = array();
$json = json_decode(file_get_contents($url));
$filter_array = array_filter($json->tag->media->nodes)); // working
foreach($filter_array as $object_return){
echo $object_return->code.'</br>'; // will output code string
}
if(!$json->tag->media->page_info->has_next_page) break;
$url = $baseUrl.'&max_id='.$json->tag->media->page_info->end_cursor;
++$count;
我还删除了此处不需要的while循环。
