Creating javascript function to destroy php session

Question

I am having trouble figuring out how to create a javascript function that will destroy a php session. I have a clickable link that will call a function called destroyphpses

Answer 1

Your JavaScript runs client-side, and your PHP runs server-side. You can't call PHP functions from JavaScript this way. You have two options:

Do an AJAX call to a server-side script that clears the session data (recommended, for consistency and proper clearing of that stuff server-side) Clear the PHPSESSID cookie with JavaScript (won't work if you reconfigure how you handle sessions, or if sessions are handled by URL parameters)
