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.
