用PHP同时登录两个网站

Question

how do I use the same web session that was created in one web app to another web app? In order words, if I login to site1.php, how do I automatically get logged in (without having to fill a form or anything) to site2.php using the same credentials that I used to login on site1.php?

Any help please

Answer 1

Your users propably get a cookie with their session id set If not, do so. Both sides would have to use the same session backend to be able to get the session for the given id (from cookie). To share sessions between websites both sites need to use the same session handler. For example in a database.
