简单的html dom帮助从使用会话的外部网页中提取数据

Question

I want to simply pull data from external url which use session. I have a website with login. after login there is a page which includs on tables data. I want to pull these data from it. Extracting data from this page is not a problem. Real problem is its includes on session. When i try to retrieve data with an url then its show an blank page. Nothing is showing. It will be great help if this problem is resolved. Please someone tell me how can i resolve this session issue? Below is my code:

$html = new simple_html_dom();<br> $html->load_file('http://example.com/portfolio/page=5');<br> foreach($html->find('body') as $e){ $array = $html->innertext;<br> echo $array;
}

If the session is used as a login or vital-information-storing variable, then it isn't possible to fake this.

Session variables are not easily spoofed, and can't be sent this way. You would have to send $_GET variables which the code then uses to create/modify the session or display the data you need without the session. It's only really feasable if you have access to www.example.com for editing the code, where you could send params which bypass the session check.

This is not reccommended as this bypass could be found by others, and you'll have a huge vulnerability.

If session variables were easily faked and passed from another page, we'd have many security risks.

If you are part of the same domain, then it is possible to start the session within the code of the calling page and have access that way...

EDIT: Unless the session is passed in the URL (bad practice, generally) it is not possible to pass session variables between domains. See here.
