session_cache_expire — Return current cache expire
Description
session_cache_expire() returns the current setting of session.cache_expire.
The cache expire is reset to the default value of 180 stored in session.cache_limiter at request startup time. Thus, you need to call session_cache_expire() for every request (and before session_start() is called).
Parameters
- new_cache_expire
-
If new_cache_expire is given, the current cache expire is replaced with new_cache_expire .
Note: Setting new_cache_expire is of value only, if session.cache_limiter is set to a value different from nocache.
Return Values
Returns the current setting of session.cache_expire. The value returned should be read in minutes, defaults to 180.
