How to accept trade offer steam through php?

Question

PHP

Hello, you need to accept the exchange coming to steam, using php, I
found the following solutions:
1st
2nd
3rd
1st and 2nd are similar, but in the 1st I did not find where to get steam cookies and how to push them into a variable.
3 did not understand how to implement.
I assume that the easiest option is the 1st one, but how then to push your cookies into the variable?
Perhaps there are other solutions?

Answer 1

The easiest is the third option, since everything has already been done for you, and you can just take it and use it. Connect the package through Composer and index.phpwrite in the file require 'vendor/autoload.php';, and then connect the desired file ( SteamCommunity.php) and work with Steam
