Hi all,
any way to count the number of users i have logged into my site?
any help/code appreciated,
craig

你真的有人用用户名/密码进行身份验证，

或者你只是想看看你的网站有多少人（独特用户）打了？b / b

Do you actually have people authenticating with usernames/passwords,
or are you just looking to see how many people (unique users) have hit
your site?

我让他们先登录，由会话设置，所以我只想说

''有X用户登录''然后列出用户名。


那件事


干杯

I have them logging in first, set by a session, so I just want to say
''There are X users logged in'' and then list the usernames.

That kinda thing

Cheers

1）***使用数据库，有一个表active_users

2）每个请求都有一个会话&登录用户，使用带有时间戳（或日期时间）字段的用户ID插入记录

，使用当前

时间，或者使用当前

时间更新已经存在的记录该信息（如果

MySQL：ON DUPLICATE KEY UPDATE节省了很多麻烦）。

3）在检查活动用户时，删除active_users中的所有条目

表更新超过X分钟前（X是您的选择）。

4）显示活跃用户中的列表。


1如果您已经使用

session_set_save_handler（）使用自定义处理程序在数据库中存储

会话，那么-3甚至更容易（也更可靠），但是如果你不要为其他

原因做这件事，因为只有活跃用户的脚本会有点过头。

1) Preferably use a database, have a table active_users
2) On each request with a session & logged in user, either insert a record
with the user-id with a timestamp (or datetime) field, with the current
time, or update an allready existing record with that information (if
MySQL: ON DUPLICATE KEY UPDATE saves a lot of hassle).
3) On checking for active users, remove all entries from the active_users
table with updated more than X minutes ago (X is your choice).
4) Display the list in active users.

1-3 are even easier (and more reliable) if you''ve taken to storing
sessions in the database with a custom handler using
session_set_save_handler(), but if you don''t do this allready for other
reasons that would be a bit over the top for only an ''active users'' script.
