PHP Sessions with disabled cookies, does it work?

"A visitor accessing your web site is assigned a unique id, the so-called session id. This is either stored in a cookie on the user side or is propagated in the URL. "

Sessions: Introduction

If session.use_cookies = 1 (Cookie enabled.)

If session.use_cookies = 0 (Cookie disabled.)

If session.use_cookies = 1 then session stores the sessionId into cookie. Calling session_id() get the stored sessionId from cookie and saved data into session array will be found on all the pages. If session.use_cookies = 0 In this case session does not store sessionId into cookie and you will get each time a new sessionId using session_id() and data stored into session on other pages will not be found on another pages.

Yes session will work when cookies is disabled. But first apache check php configuration settings. Like:

   --enable-trans-sid
and
   --enable-track-vars

if these value are set true the session will passed by POST automatically.

If "--enable-trans-sid" and "--enable-track-vars" values are set to FALSE, we need to pass session id by using the SID constant.

< a href="index.php?<?= SID ?>" >Navigate from here< /a >

Need to set php.ini

ini_set("session.use_cookies", 0);
ini_set("session.use_trans_sid", 1);
