ini_set('session.cache_limiter','public');
session_cache_limiter(false);

 

they give warning

Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time in C:\xampp\htdocs\aps\init.php on line 3

Warning: session_cache_limiter(): Cannot change cache limiter when session is active in C:\xampp\htdocs\aps\init.php on line 4

As both error messages clearly state, you cannot change session settings after you've already started the session. It should logically follow that if you want to change settings then you have to do it before the session is started.

so this means

ini_set('session.cache_limiter','public');

session_cache_limiter(false);

session_start();

 

or

session_start();

ini_set('session.cache_limiter','public');

session_cache_limiter(false);

 

and what happen when am creating login  session

One of those two will work and the other will not.

What will happen is, if you do the correct method then it will work, and if you do the incorrect method then it will not work.

BUT if you use the incorrect method in the same execution as the correct method, then the success or lack of would be based on the order of execution and which may or may not be due the position of the code in the said file.
