I'm new and i'm looking for a solution for my problem.
There is an external website returning a value after the compilation of a two inputs form. I want to catch the page sending a value in my PHP page.
My purpose is to verify if the external website says "true" or "false" to a request. I have already created something like that for GET results checking every word of the external page in order to find "True" or "false".
How can i do the same thing with a POST request?
...And (another request) how can i do the same thing with a form that use SESSIONS where it saves the fields of the form?
Thanks in advance and sorry for my "english" (i'm italian ;) )
