php - Codeigniter - How to get Other user session -

-


i'm using chat in codeigniter here i'm tring active users can display in chat whether user online or offline. tried following result empty.

$this->session->all_userdata();

kindly me.

if using database sessions, potentially verify login status using call ci_sessions table (or whatever have named it). can use simple query validate if have been browsing within last hour (or whatever) , validate them being online.

sample sql query this:

select from_unixtime(timestamp) 'timestamp' ci_sessions timestamp > unix_timestamp(date_add(curdate(),interval -1 hour)) order timestamp desc

this return users active in last hour (the timestamp col updated each time page requested)

you can grab users details out of 'data' column...

$this->session->all_userdata()

will not return logged in users available data of current logged in user

Deploying Qt Application on Android is really slow? -

as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
