你好， 我希望你有美好的一天。
我有一个问题。我正在参考Simple HTML DOM的官方文档进行学习。我成功抓取了公告板上的帖子列表，但在尝试通过各自的链接抓取每个帖子的内容时失败了。
当我添加以下代码时：
$detail_html = file_get_html($link);
echo $detail_html->find('.view-content', 0)->text();
我遇到错误：
Fatal error: Uncaught Error: Call to a member function text() on null in /home/simple/public_html/test.php:23 Stack trace: #0 {main} thrown in /home/simple/public_html/test.php on line 23
如果您有任何解决方案或建议，请告诉我。由于这个问题是通过 ChatGPT 翻译的，所以听起来可能有点尴尬。谢谢你。
我尝试使用帖子链接抓取内容。
当您检索链接时，它将如下所示。
https://sample-ex.com/bbs/board.php?bo_table=free&wr_id=238你可以使用
str_replace$detail_html = file_get_html(str_replace('&', '&', $link);
