推荐答案
文件 simple_html_dom.php
不是你告诉PHP要查找的地方。
The file simple_html_dom.php
is not where you're telling PHP to look for it.
require_once('../simple_html_dom.php');
为安全起见,请尝试使用完整路径而不是相对路径。
To be safe, try using the full path instead of a relative path.
require_once('E:\wamp\www\in.com\components\simple_html_dom.php');
BTW,如果上面的完整路径不正确,那么这就是你的问题。这是PHP正在尝试的路径。
BTW, if the full path above is incorrect, then that is your problem. This is the path that PHP is trying.
澄清:我只是建议OP切换到绝对路径来识别和确认问题的根源。以绝对路径进行生产很少是一个好主意。
To clarify: I'm only suggesting the OP switch to absolute paths to identify and confirm the source of the issue. Going to production with absolute paths is rarely a good idea.
