How to parse different pages on a site with authorization?

Question

PHP

Hello.
There is a need to parse some data in your account of one service. I use cURL for authorization, it turned out well to authorize, but there was a difficulty at the stage when you need to go through several categories, each category has a pager, where there can be a dozen more pages. It turns out that I can’t use file_get_contents(), and for each next page, opening a new curl session is too bold in my opinion, including the code ... How to accurately solve my problem? How do people generally act in such a case? Maybe I missed some point? Can you show an example how to do this?
UPD:
I was hoping, just that there is some way to log in, close the cURL session and then process data, take other pages, and so on outside the session ...

Answer 1

why file_get_contents when you use curl? without closing the session just open another page

$handle = curl_init();
curl_setopt($handle, CURLOPT_URL, 'fantasyland.ru/login.php');
curl_setopt($handle, CURLOPT_POST, 1);
curl_setopt($handle, CURLOPT_POSTFIELDS, 'login=ххх&password=ххх');
curl_setopt($handle, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($handle, CURLOPT_HEADER, 0);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($handle, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($handle, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_exec($handle);

curl_setopt($handle, CURLOPT_URL, 'fantasyland.ru/cgi/v_trade_load_all.php');
$page = curl_exec($handle);
