Question

How to delete a php session by name For example, I session['sec'] and session['page'] I need to delete session['page'] without deleting session['sec']

Answer 1

 // for a single variable unset($_SESSION['session_var']); // destroy the Session, not just the data stored! session_destroy(); // delete the session contents, but keep the session_id and name: session_unset(); 

Answer 2

This should do it:

 unset($_SESSION['page']); 

Answer 3

In this case, you are not deleting the session, but only the session variable. So simple:

 unset($_SESSION['page']);
