Passing/loading session id between domains

[akido]

I have a problem that's driving me nuts. I've googled and searched for hours 🙁

Anyways..

I have a program that I call a login API from. It returns a PHP session ID.

Problem is I call this from PHP and thus the session is not assigned to the browser.

I need this session ID to be loaded in order to actually log the client in.

How do I pass this session ID back to the software to be loaded?

You can't. PHP is a server-side language, meaning you can not read/write anything to the client's end. You will need to be looking at another solution outside of PHP. If you use another piece of software (like Java or C) you can use that to embed a browser that goes to a special URL like yoursite.com/session_id.php which only returns the result and read that result to a stream or something. Be creative, but PHP is not going to be able to do what you want (if I understand you correctly).

So if I have the session id, I can't tell php to load that session for the client? Hmm.

I was told I could, but not sure how. If the session exists, I can't tell php to use that session when it's being created on the client end?

It was actually really simple, I just created a page with almost no code in it:

$SessionID (used curl here to parse out xml and get session id)
session_id($SessionID);
session_start(); 
header('location of area I want to go');
