# 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` ] )

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_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

/* 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";
