Return current cache expire
int session_cache_expire ([ string $new_cache_expire ] )
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_expire 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.
Returns:
Returns the current setting of session.cache_expire. The value returned should be read in minutes, defaults to 180.
Examples:
session_cache_expire() example
<?php /* set the cache limiter to 'private' */ session_cache_limiter('private'); $cache_limiter = session_cache_limiter(); /* set the cache expire to 30 minutes */ session_cache_expire(30); $cache_expire = session_cache_expire(); /* start the session */ session_start(); echo "The cache limiter is now set to $cache_limiter<br />"; echo "The cached session pages expire after $cache_expire minutes"; ?>
