Sessions can be configured in your php ini file or in your  htaccess file  Have a look at the PHP session documentation   What you basically want to do is look for the line session cookie lifetime in php ini and make it s value is 0 so that the session cookie is valid until the browser is closed  If you can t edit that file  you could add php value session cookie lifetime 0 to your  htaccess file

The sessions on PHP works with a Cookie type session  while on server-side the session information is constantly deleted   For set the time life in php  you can use the function session set cookie params  before the session start    session set cookie params 3600       session start      For ex  3600 seconds is one hour  for 2 hours 3600 2   7200   But it is session cookie  the browser can expire it by itself  if you want to save large time sessions  like remember login   you need to save the data in the server and a standard cookie in the client side   You can have a Table  Sessions     session id int session hash varchar 20  session data text   And validating a Cookie  you save the  session id  and the  hash   for security  on client side  and you can save the session s data on the server side  ex   On login   setcookie  sessid    sessionid  604800           One week or seven days setcookie  sesshash    sessionhash  604800       One week or seven days    And save the session data  saveSessionData  sessionid   sessionhash  serialize   SESSION       saveSessionData is your function   If the user return   if  isset   COOKIE  sessid           if  valide session   COOKIE  sessid      COOKIE  sesshash                 SESSION   unserialize get session data   COOKIE  sessid            else              Dont validate the hash  possible session falsification           Obviously  save all session cookies calls  before sending data

Prior to PHP 7  the session start   function did not directly accept any configuration options  Now you can do it this way   lt  php    This sends a persistent cookie that lasts a day  session start        cookie lifetime    gt  86400        gt    Reference  https   php net manual en function session-start php example-5976
