How do I delete PHPSESSID on client computers

Question

UPDATE ON THE PROBLEM:

• On some browsers, we have two PHPSESSIDs.
• One PHPSESSID is not set by me anywhere in my script
• It has

Answer 1

Lets go back to basics - Here is something that I believe you should try: Run your site. Keep a note of PHPSESSID. then close the browser completely, open the browser again, and then run your site. Check the PHPSESSID and see if it is the same.

If it is not same then it is not a cookie but a Session ID specific for the browser session. Second, if the PHPSESSID is the same as set the first time then it is a cookie and you 'will' be able to delete any key=>value pair set to the cookie resources. May be you are referencing something wrong in the JS or PHP code.

Please try this and revert with results. It will give a lot more clarity. Sessions, LocalStorage, IndexDB, Cookies all are different things and referenced differently.
