检查 PHP 会话是否处于活动状态; [英] Check if a PHP session is active;
问题描述
基本上我想要实现的是这个,下面的不起作用,但你应该明白.
Basically what I am trying to achieve is this, the below does not work but you should get the idea.
if (session_status() == PHP_SESSION_ACTIVE) {
show specific icons
}
else
{
don't show specific icons
}
我做错了什么.如何可靠地检查会话是否在 php 5.4 中启动.我在某处读到这是推荐的方法.
What am I doing wrong. How can I reliably check if a session is started in php 5.4. I have read somewhere that this is the recommended way.
推荐答案
session_status 适用于 PHP v5.4 及更高版本,也许这就是原因.
session_status is available for PHP v5.4 and later, maybe that's why.
您可以尝试使用 session_id :
session_id() 返回当前会话的会话 ID,如果没有当前会话(当前会话 ID 不存在),则返回空字符串 ("").
session_id() returns the session id for the current session or the empty string ("") if there is no current session (no current session id exists).
正是您在 5.4 以下 PHP 所需要的!;)
Just what you need for PHP below 5.4 ! ;)
