cleanup php session files

To handle session properly, take a look at http://php.net/manual/en/session.configuration.php.

There you’ll find these variables:

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

These control the garbage collector (GC) probability of running with each page request.

You could set those with ini_set() at the beginning of your script or .htaccess file so you get certainty to some extent they will get deleted sometime.
