How to perform an action?

Question

PHP

There is such a site -.
It has a tab - how to access the Internet version of the ITS.
Inside there is a form by which you can find out if the contract is connected to the Internet version.
Further. There is another site. It is necessary that a person enters the number of his contract there and displays whether it is connected or not. The difficulty is that it turns out that you need to somehow send the form data to another form. Any ideas?

Answer 1

There is an idea to connect on both to the same database ;-)

Answer 2

It is necessary to track what and in what form the site transmits to the server and what it receives in response, and then use it at home. Those. you send a similar request from your site to the server of the second site and display the response. You may have to tinker with the settings if there are some restrictions, for example, on the host or ip-address from which requests come.
