In managing and using one project I find I need to know if no user is active in the live website, as they might be entering data that I might interrupt. Then I know I can turn on the maintenance mode and do updates to the website.
So I have written this helper function that is perhaps IonAuth- specific, but that helps me to find out that data. You can put it into a file in the helper directory (app/Helpers), load it into your project as a helper, and get the list of active users this way:
PHP Code:
$active_users = active_sessions();
Here is the function itself. If anyone has suggestions how to make it less dependent on IonAuth and more error-prone, please let me know. Hope it will be useful. I have commented it extensively to make the sphagetti-code more clear.
PHP Code:
function active_sessions()
{
$config = config('App');
helper('filesystem');
$map = directory_map(WRITEPATH . '/session');
//get names and dates of the session files
foreach ($map as $file) {
$file_data[] = get_file_info(WRITEPATH . '/session/' . $file, ['name', 'date']);
}
// set the variables to be used:
//get timestamp before which the sessions are expired
//current time minus the session expiration time
$session_threshold = time() - $config->sessionExpiration;
//last movement within system variable
$last_movement = $session_threshold;
// array of active users
$active_users = array();
//cycle through the file list
foreach ($file_data as $key => $value) {
if ($value['date'] > $session_threshold) {
//read file contents
// they look something like, must be ion_auth-specific:
// '__ci_last_regenerate|i:1633202933;_ci_previous_url|s:34:"http://site.com/page";identity|s:13:"[email protected]";email|s:13:"[email protected]";user_id|i:44;old_last_login|i:1633114505;last_check|i:1633197212;%
$filec = file_get_contents(WRITEPATH . '/session/' . $value['name'], true);
//exclude cases which include your own email and which do not include the email variable:
if (!strpos($filec, $_SESSION['email']) && strpos($filec, 'email')) {
// in case of a match, explode the file and get the email variable
$data = explode("\"", $filec);
foreach ($data as $datum) {
if (strpos($datum, "@")) {
$active_users[$datum] = $datum; //this way only unique emails are preserved
// if the timestamp of the file is newer than the current in variable
// replace old with new; the end result should be the last
// user movement time
if ($last_movement < $value['date']) {
$last_movement = $value['date'];
}
break;
}
}
};
}
}
//set the data to return
$data['users'] = $active_users; //list of user emails
$data['last_movement'] = gmdate("Y-m-d H:i:s", $last_movement + date("Z")); //last movement
return $data;
}
