How to automatically delete session files?

Question

PHP

When visiting a site, a large number of empty session files are created and the entire disk space is filled up quite quickly.
The session settings are set at the start of the script for 10 minutes. But the files are not deleted automatically. What should I do to remove them?

ini_set('session.save_path', $_SERVER['DOCUMENT_ROOT'] .'/sessions/');
ini_set('session.gc_maxlifetime', 600);
ini_set('session.cookie_lifetime', 600);

Answer 1

.htaccess
php_value session.gc_divisor 1
php_value session.gc_probability 2
garbage collector not working most likely either
