如何通过名称删除会话

Question

如何通过名称 比如我有session['sec']和session['page']我需要删除session['page']与删除PHP会话进行删除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(); 

Answer 2

这应做到：

unset($_SESSION['page']); 

Answer 3

你止跌在这种情况下，不会删除会话，只会话变量。所以只是做：

unset($_SESSION['page']);
