How to properly parse the image selection form and display its direct link?

Question

PHP

Hello, don’t kick me in advance, I’m new to php.
I would like to constructively understand how to parse the image selection page and display its direct link if it is available, how to implement it correctly, I googled that it can be done via curl or file_get_contents
How to send requests correctly, display the result after submitting the form?
Ideally, I would be very grateful if you show by example how to display the form on your page of this site:
https://1fichier.com (image hosting)
select all the parameters that are on the main page, and when you click on the send button, display a direct link to the uploaded image Online
