PHP5中文手册·Return current cache expire -- 追寻梦想＞编程乐园＞PHP 编程

说明

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).

参数

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.

返回值

Returns the current setting of session.cache_expire. The value returned should be read in minutes, defaults to 180.

范例

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";
?>
