session_cache_expire
(PHP 4 >= 4.2.0, PHP 5)
session_cache_expire — Return current cache expire
Description
int session_cache_expire
([ int $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).
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.
Return Values
Returns the current setting of session.cache_expire.
The value returned should be read in minutes, defaults to 180.
Examples
Example #1 session_cache_expire() example

$cache_expire = session_cache_expire();
session_start();
echo "The cache limiter is now set to $cache_limiter<br />";

?>
