Session Funcions in Php

session.name string
session.name specifies the name of the session which is used as cookie name. It should only contain alphanumeric characters. Defaults to PHPSESSID. See also session_name().

session.auto_start boolean
session.auto_start specifies whether the session module starts a session automatically on request startup. Defaults to 0 (disabled).

session.serialize_handler string
session.serialize_handler defines the name of the handler which is used to serialize/deserialize data. Currently, a PHP internal format (name php) and WDDX is supported (name wddx). WDDX is only available, if PHP is compiled with WDDX support. Defaults to php.

session.gc_probability integer
session.gc_probability specifies the probability that the gc (garbage collection) routine is started on each request in percent. Defaults to 1.

session.gc_maxlifetime integer
session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up.

Note: If you are using the default file-based session handler, your filesystem must keep track of access times (atime). Windows FAT does not so you will have to come up with another way to handle garbage collecting your session if you are stuck with a FAT filesystem or any other fs where atime tracking is not available.

session.referer_check string
session.referer_check contains the substring you want to check each HTTP Referer for. If the Referer was sent by the client and the substring was not found, the embedded session id will be marked as invalid. Defaults to the empty string.

session.entropy_file string
session.entropy_file gives a path to an external resource (file) which will be used as an additional entropy source in the session id creation process. Examples are /dev/random or /dev/urandom which are available on many Unix systems.

session.entropy_length integer
session.entropy_length specifies the number of bytes which will be read from the file specified above. Defaults to 0 (disabled).

session.use_cookies boolean
session.use_cookies specifies whether the module will use cookies to store the session id on the client side. Defaults to 1 (enabled).

session.use_only_cookies boolean
session.use_only_cookies specifies whether the module will only use cookies to store the session id on the client side. Defaults to 0 (disabled, for backward compatibility). Enabling this setting prevents attacks involved passing session ids in URLs. This setting was added in PHP 4.3.0.

session.cookie_lifetime integer
session.cookie_lifetime specifies the lifetime of the cookie in seconds which is sent to the browser. The value 0 means "until the browser is closed." Defaults to 0.See also session_get_cookie_params() and session_set_cookie_params().

session.cookie_path string
session.cookie_path specifies path to set in session_cookie. Defaults to /.See also session_get_cookie_params() and session_set_cookie_params().

session.cookie_domain string
session.cookie_domain specifies the domain to set in session_cookie. Default is none at all. See also session_get_cookie_params() and session_set_cookie_params().

session.cookie_secure boolean
session.cookie_secure specifies whether cookies should only be sent over secure connections. Defaults to off. This setting was added in PHP 4.0.4. See also session_get_cookie_params() and session_set_cookie_params().

session.cache_limiter string
session.cache_limiter specifies cache control method to use for session pages (none/nocache/private/private_no_expire/public). Defaults to nocache. See also session_cache_limiter().

session.cache_expire integer
session.cache_expire specifies time-to-live for cached session pages in minutes, this has no effect for nocache limiter. Defaults to 180. See also session_cache_expire().

session.use_trans_sid boolean
session.use_trans_sid whether transparent sid support is enabled or not. Defaults to 0 (disabled).
