[求助]session()是不是没有过期时间？
刚开始学做php，给客户做的东西，他们提出session()过期时间太长，一两个小时还不过期，这怎么解决啊？<BR> int session_cache_expire ( [int new_cache_expire])<br><br><br>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. <br><br>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). <br><br>例子 1. session_cache_expire() example<br><br><?php<br><br>/* set the cache limiter to 'private' */<br><br>session_cache_limiter('private');<br>$cache_limiter = session_cache_limiter();<br><br>/* set the cache expire to 30 minutes */<br>session_cache_expire(30);<br>$cache_expire = session_cache_expire();<br><br>/* start the session */<br><br>session_start();<br><br>echo "The cache limiter is now set to $cache_limiter</ br>";<br>echo "The cached session pages expire after $cache_expire minutes";<br>?> <br> <br>页:
