SESSION_CACHE_EXPIRE(3) 1 SESSION_CACHE_EXPIRE(3)
session_cache_expire - Return current cache expire
SYNOPSIS
int session_cache_expire ([string $new_cache_expire])
DESCRIPTION
session_cache_expire(3) returns the current setting of session.cache_expire.
The cache expire is reset to the default value of 180 stored in session.cache_expire at request startup time. Thus, you need to call ses-
sion_cache_expire(3) for every request (and before session_start(3) is called).
PARAMETERS
o $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.
