[Session] ; Handler used to store/retrieve data . //用于存储和检索与会话关联数据的处理器名字 session.save_handler = files ; Argument passed to save_handler. In the case of files, this is the path ; where data files are stored. Note: Windows users have to change this ; variable in order to use PHP's session functions. ; ; As of PHP 4.0.1, you can define the path as: ; ; session.save_path = "N;/path" ; ; where N is an integer. Instead of storing all the session files in ; /path, what this will do is use subdirectories N-levels deep, and ; store the session data in those directories. This is useful if you ; or your OS have problems with lots of files in one directory, and is ; a more efficient layout for servers that handle lots of sessions. ; ; NOTE 1: PHP will not create this directory structure automatically. ; You can use the script in the ext/session dir for that purpose. ; NOTE 2: See the section on garbage collection below if you choose to ; use subdirectories for session storage //如果使用前述的目录方式存储session，则php自动垃圾回收机制将会失效； ; ; The file storage module creates files using mode 600 by default. ; You can change that by using ; ; session.save_path = "N;MODE;/path" ; ; where MODE is the octal representation of the mode. Note that this ; does not overwrite the process's umask. ;session.save_path = "/tmp" ; Whether to use cookies.//是否在客户端使用cookie保存会话ID session.use_cookies = 1 ;session.cookie_secure = //是否仅通过https安全连接发送cookie ; This option enables administrators to make their users invulnerable to ; attacks which involve passing session ids in URLs; defaults to 0. ; session.use_only_cookies = 1//确定是否仅仅使用cookie在客户端保存回话ID，如果打开可以避免使用URL传递会话带来的安全隐患；但是禁用cookie的客户端将无法使用会话； ; Name of the session (used as cookie name). session.name = PHPSESSID //默认的cookie会话中存储的会话ID，只可以包含字母和数字 ; Initialize session on request startup. session.auto_start = 0//是否默认开启session会话控制，如果开启则会话中就不可以保存对象 ; Lifetime in seconds of cookie or, if 0, until browser is restarted. session.cookie_lifetime = 0//设定传递会话ID的cookie有效期，如果为0，则在浏览器重启后失效； ; The path for which the cookie is valid. session.cookie_path = / ; The domain for which the cookie is valid. session.cookie_domain = //表示传递回话ID的作用路径 ; Whether or not to add the httpOnly flag to the cookie, which makes it inaccessible to browser scripting languages such as JavaScript. session.cookie_httponly = //是否设定在cookie中添加httponly标志，如果开启则只会导致客户端脚本得不到该cookie； ; Handler used to serialize data. php is the standard serializer of PHP. session.serialize_handler = php //设定用来序列化、解序列化的处理器，也可以使用php_binary；当启用了WDDX支持后，这只可以使用 wddx处理器 ; Define the probability that the 'garbage collection' process is started ; on every session initialization. ; The probability is calculated by using gc_probability/gc_divisor, ; e.g. 1/100 means there is a 1% chance that the GC process starts ; on each request. session.gc_probability = 1 session.gc_divisor = 100 //设定每次初始化会话时，启动垃圾回收程序的概率；如果会话页面访问越频繁，则概率就应该越小；一般设定在1/1000-5000 ; After this number of seconds, stored data will be seen as 'garbage' and ; cleaned up by the garbage collection process. session.gc_maxlifetime = 1440 ; NOTE: If you are using the subdirectory option for storing session files ; (see session.save_path above), then garbage collection does *not* ; happen automatically. You will need to do your own garbage ; collection through a shell script, cron entry, or some other method. ; For example, the following script would is the equivalent of ; setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes): ; cd /path/to/sessions; find -cmin +24 | xargs rm ; PHP 4.2 and less have an undocumented feature/bug that allows you to ; to initialize a session variable in the global scope, albeit register_globals ; is disabled.
