PHP - Manual手册 - Function Reference函数参考 - Session Extensions会话扩展 - Session Handling会话操作 - Installing/Configuring安装/配置 - Runtime Configuration运行时配置 - session.save_path 定义了传递给存储处理器的参数

session.save_path string session.save_path defines the argument which is passed to the save handler. If you choose the default files handler, this is the path where the files are created. See also session_save_path().
There is an optional N argument to this directive that determines the number of directory levels your session files will be spread around in. For example, setting to '5;/tmp' may end up creating a session file and location like /tmp/4/b/1/e/3/sess_4b1e384ad74619bd212e236e52a5a174If . In order to use N you must create all of these directories before use. A small shell script exists in ext/session to do this, it's called mod_files.sh. Also note that if N is used and greater than 0 then automatic garbage collection will not be performed, see a copy of php.ini for further information. Also, if you use N, be sure to surround session.save_path in "quotes" because the separator (;) is also used for comments in php.ini.
Warning
If you leave this set to a world-readable directory, such as /tmp (the default), other users on the server may be able to hijack sessions by getting the list of files in that directory.


Note: Prior to PHP 4.3.6, Windows users had to change this variable in order to use PHP's session functions. A valid path must be specified, e.g.: c:/temp.
