Of course. Otherwise, is it still called a session? SESSION is used to save data across pages.
PHP sessions can be stored in php. the configuration in ini is saved in file, memcache, or redis. In memcache, each session is saved with a key name starting with php. The survival time is based on the settings in the configuration, default Value: 1440 seconds.
