How to pass the authorization cookie file_get_contents to get the marketplace page and active lots of a Steam user?

Question

PHP

Good afternoon. There is a steam page https://steamcommunity.com/market/ . On this page there is a tab - Active lots and to see them, you need to log in to the site. How can I authorize through steam on my site (presumably this is OpenId) and display the page https://steamcommunity.com/market/ through file_get_contents to display active lots, presumably we need to send authorization cookies somehow to file_get_contents and then we will receive the page with an authorized steam user.
What can you say about this?
