That button sends an AJAX request that runs wp_ajax_destroy_sessions(). It’s not really abstracted in such a way that you can re-use it outside of AJAX, but if you copy the source into your own function, minus the JSON parts, then you could perform the same action yourself.

You could create a dummy user (with no rights) and log in every visitor using this dummy user. This could be done pretty easily: wp_set_auth_cookie($uid, true); wp_set_current_user($uid); But in my opinion that’s a rather flawy workaround. Your main problem is that all pages for not-logged-in users come from the page-cache. That also means that all … Read more
There is no regular output and hence no header sent before template_redirect on the front end. If you need sessions on the back end too, use the action wp_loaded to cover both. Example: add_action( ‘template_redirect’, function() { $status = session_status(); if ( PHP_SESSION_DISABLED === $status ) { // That’s why you cannot rely on sessions! … Read more
