What's the default session lifetime in PHP? Can it be changed?

Answer 1

You can get your default session life time by doing this:

echo ini_get('session.gc_maxlifetime');

To set your own session life time or to extend it, do this:

ini_set('session.gc_maxlifetime', 30*60); // Can be changed to anything in seconds

Answer 2

To get:

ini_get('session.gc_maxlifetime');

To set:

ini_set(‘session.gc_maxlifetime’,SOME_VALUE);

Answer 3

It's in your php.ini file. It defaults to 24 minutes, but it's easy to change.

Look for session.gc_maxlifetime and set to to the value you want in seconds.

Answer 4

The default in the php.ini for the session.gc_maxlifetime directive (the "gc" is for garbage collection) is 1440 seconds or 24 minutes.
