php - 如何按名称删除 session

Question

如何通过名称删除 php session 例如我有 session['sec'] 和 session['page'] 我需要删除 session['page'] 而不删除 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();
