I want to delete session files automatically in PHP.

I came to know that I have to change the following configurations in PHP.ini

  • session.gc_probability
  • session.gc_divisor
  • session.gc_maxlifetime

But I am not sure that what value to change in these properties.

    If you keep the PHP save session path to default, PHP should automatically clear them up. If you change the path, you have to clean it yourself. – Clarkey Aug 26 '14 at 08:52
  • What do you mean automatically? After a certain time period or when the user logs out? – Chris Aug 08 '15 at 15:12
  • [This question](https://stackoverflow.com/questions/654310/cleanup-php-session-files) has useful information about the automatic session file cleanup. – T30 May 25 '17 at 10:00

Probably this example will help you

 <?php 
 // you have to open the session to be able to modify or remove it 
 session_start(); 

 // to change a variable, just overwrite it 
 $_SESSION['variable_name']='variable_value'; 

 //you can remove a single variable in the session 
 unset($_SESSION['variable_name']); 

 // or this would remove all the variables in the session, but not the session itself 
 session_unset(); 

 // this would destroy the session variables 
 session_destroy(); 
 ?>

    Usually for removing the session files, there is a CRON that deletes them. Do you have full access to the server? – Chris Aug 08 '15 at 15:13

Using session_destroy(); function, created session files deleted from automatically.
