session_cache_expire
(PHP 4 >= 4.2.0)
session_cache_expire -- Return current cache expire
Description
int session_cache_expire ( [int new_cache_expire])
session_cache_expire() returns the current setting of session.cache_expire.
The value returned should be read in minutes, defaults to
180. If new_cache_expire is given, the current cache expire
is replaced with new_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).
Example 1. 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";
?>
Note: Setting new_cache_expire is of value only, if session.cache_limiter
is set to a value different from nocache.
See also the configuration settings session.cache_expire,
session.cache_limiter and session_cache_limiter().
