I have this function to start a secure session:
function sec_session_start() {
$session_name = 'sec_session_id'; // Set a custom session name
$secure = false; // Set to true if using https.
$httponly = true; // This stops javascript being able to access the session id.
ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies.
$cookieParams = session_get_cookie_params(); // Gets current cookies params.
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
session_name($session_name); // Sets the session name to the one set above.
session_start(); // Start the php session
session_regenerate_id(true); // regenerated the session, delete the old one.
}
How do I set my cookies to expire whenever the user navigates away from my app or closes their browser? Basically, every time a user visits my app, they need to login again.
A lifetime of 0 (which is usually the default for session cookies) does precisely what you described. See http://us3.php.net/manual/en/session.configuration.php#ini.session.cookie-lifetime

I am working to upgrade my domain in php 7.3 but when I do that one of my quiz.php file not work it says :
Could not initiate a safe session (ini_set).
I mention that in 7.1 it works quite well so I think the problem is to my function.php file in function sec_session. I will show you the code without any change from 7.1.
<?php
include_once 'psl-config.php';
function sec_session_start() {
$session_name = 'sec_session_id'; // Set a custom session name
$secure = SECURE;
// This stops JavaScript being able to access the session id.
$httponly = true;
// Forces sessions to only use cookies.
if (ini_set('session.use_only_cookies', 1) === FALSE) {
header("Location: ../error.php?err=Could not initiate a safe session (ini_set)");
exit();
}
// Gets current cookies params.
$cookieParams = session_get_cookie_params();
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
// Sets the session name to the one set above.
session_name($session_name);
session_start(); // Start the PHP session
session_regenerate_id(); // regenerated the session, delete the old one.
}
I made login system which works fine on localhost, but when is on online server it doesnt work. There arent any errors, even if I type in wrong password, no errors. Nothing happens, it is on the same page always. [http://sportcaffe.me/admin/] <- You could try here, and see what it happens..

I found some solution but it is not good... I can set session_start() on top of my code and It will work, but I have some session "prepare" and then start..
Here is my code:
$session_name = 'sec_session_id'; // Set a custom session name
$secure = FALSE;
// This stops JavaScript being able to access the session id.
$httponly = true;
// Forces sessions to only use cookies.
if (ini_set('session.use_only_cookies', 1) === FALSE) {
header("Location: ../error.php?err=Could not initiate a safe session (ini_set)");
exit();
}
// Gets current cookies params.
$cookieParams = session_get_cookie_params();
session_set_cookie_params($cookieParams["lifetime"],
$cookieParams["path"],
$cookieParams["domain"],
$secure,
$httponly);
// Sets the session name to the one set above.
session_name($session_name);
session_start(); // Start the PHP session
session_regenerate_id(); // regenerated the session, delete the old one.
I've several pages who are called by ajax to print a response,
The pages uses $_SESSION variables, so I have to use session_start().
I noticed that from time to time the pages erase the session data (and user gets disconnected) , i'm using a bit different session_start() :
function sec_session_start() {
$session_name = 'pentago'; // Set a custom session name
$secure = false; // Set to true if using https.
$httponly = false; // This stops javascript being able to access the session id.
ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies.
$cookieParams = session_get_cookie_params(); // Gets current cookies params.
session_set_cookie_params($cookieParams['lifetime'], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
session_name($session_name); // Sets the session name to the one set above.
session_start(); // Start the php session
session_regenerate_id(true); // regenerated the session, delete the old one.
}
Is there something in my custom session_start() that causes the response pages to delete the session ?
Thank you.
i created user login system and with this function i start sessions
function sessionStart() {
$session_name = 'sec_session_id'; // Set a custom session name
$secure = false; // Set to true if using https.
$httponly = true; // This stops javascript being able to access the session id.
ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies.
$cookieParams = session_get_cookie_params(); // Gets current cookies params.
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
session_name($session_name); // Sets the session name to the one set above.
session_start(); // Start the php session
session_regenerate_id(true); // regenerated the session, delete the old one.
}
i use sessions cookie just as you can see in function which i menotioned above i store this sessions in memcached to boost up my operation.now i need to create a cookie which store user data in it.for example i need user id then i store user id in cookie like this
setcookie('userid','1234',time()+240000)
and after that i need user password and username in case of keep user logged in.but i know i should not keep password in cookie.if not keeping password in cookie when our server crashes because of using memcache we will loose all users session.am i right?then how should i keep user logged in..please just explain.no need to bother yourself to writing code.
thanks in advance
I suggest you to keep your client logged-in data in a SQL database and give the SQL row a random salt + hash and then assign that hash to a cookie. Then you just fetch the info from the database each time.
My PHP sessions are expiring randomly and rarely last more than approximately 5 mins (300 secs).
I am experimenting with the PHP & MySQL login script here: http://www.wikihow.com/Create-a-Secure-Login-Script-in-PHP-and-MySQL (sec_session_start function extracted below).
function sec_session_start() {
$session_name = 'sec_session_id'; // Set a custom session name
$secure = false; // Set to true if using https.
$httponly = true; // This stops javascript being able to access the session id.
ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies.
$cookieParams = session_get_cookie_params(); // Gets current cookies params.
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $cookieParams["domain"], $secure, $httponly);
session_name($session_name); // Sets the session name to the one set above.
session_start(); // Start the php session
session_regenerate_id(true); // regenerated the session, delete the old one.
}
I have done extensive reading into the subject to try and solve the problem and understand that many reasons cause PHP sessions to expire prematurely. If you have any ideas about how I could solve the problem please let me know as the problem's driving me mad!
Please note:
1. In php.ini I have set session.gc_maxlifetime = 3600
2. My host is IPage.
2. I have tried editing session_set_cookie_params to the following, but it doesn't solve the problem:
session_set_cookie_params( time()+1800, "/", $cookieParams["domain"], $secure, $httponly);
Your code has a single, unchanging name for every single session? Have you considered that every time someone starts a new session it will clobber the previous one? There is a reason why session identifiers are unique.
Aside from that, ask your host. They might be doing something ridiculous like clearing /tmp every X minutes.
I have a similar login script, and found the solution when I looked at the cookies I was setting. For some reason this script will set cookies for both example.com and www.example.com when a brand new session is started. Explicitly setting your domain in session_set_cookie_params() will fix this behavior.
function sec_session_start() {
$domain = 'example.com'; // note $domain
$session_name = 'sec_session_id'; // Set a custom session name
$secure = true; // Set to true if using https.
$httponly = true; // This stops javascript being able to access the session id.
ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies.
$cookieParams = session_get_cookie_params(); // Gets current cookies params.
session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"], $domain, $secure, $httponly); // note $domain
session_name($session_name); // Sets the session name to the one set above.
session_start(); // Start the php session
session_regenerate_id(true); // regenerated the session, delete the old one.
}
it might be same issue as described here:
http://www.php.net/manual/en/function.session-regenerate-id.php#84242
it is browser issue, not php. (Way easier to recreate in Firefox than Chrome)
Setting "session_regenerate_id(false);" helps, but that defeats the purpose of secure login.
