session_cache_expire
Get and/or set current cache expire
Description
intfalse session_cache_expire(intnull $value = null)
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 session_cache_expire for every
request (and before session_start is called).
Parameters

If value is given and not null, the current cache
expire is replaced with value.
Note:
Setting value is of value only, if
session.cache_limiter is set to a value
different from nocache.
Return Values

The value returned should be read in minutes, defaults to 180.
On failure to change the value, false is returned.
