SESSION_CACHE_EXPIRE(3) 						 1						   SESSION_CACHE_EXPIRE(3)

session_cache_expire - Return current cache expire

SYNOPSIS

       int session_cache_expire ([string  $new_cache_expire])

DESCRIPTION

       session_cache_expire(3) returns the current setting of session.cache_expire.

	The  cache expire is reset to the default value of 180 stored in session.cache_expire at request startup time. Thus, you need to call ses-
       sion_cache_expire(3) for every request (and before session_start(3) is called).

PARAMETERS

	      o $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.

RETURN VALUES

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

EXAMPLES

       Example #1

	      session_cache_expire(3) 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";
	      ?>

session_name - Get and/or set the current session name

SYNOPSIS

       string session_name ([string  $name])

DESCRIPTION

       session_name(3) returns the name of the current session. If $name is given, session_name(3) will update the session name and return the old
       session name.

	The session name is reset to the default value stored in session.name at request startup time. Thus, you need to call session_name(3)  for
       every request (and before session_start(3) or session_register(3) are called).

PARAMETERS

	      o $name
		- The session name references the name of the session, which is used in cookies and URLs (e.g.	PHPSESSID). It should contain only
		alphanumeric characters; it should be short and descriptive (i.e. for users with enabled cookie warnings). If $name is	specified,
		the name of the current session is changed to its value.

	      Warning

		      The  session name can't consist of digits only, at least one letter must be present. Otherwise a new session id is generated
		     every time.

RETURN VALUES

	Returns the name of the current session. If $name is given and function updates the session name, name of the old session is returned.

EXAMPLES

       Example #1

	      session_name(3) example

	      <?php

	      /* set the session name to WebsiteID */

	      $previous_name = session_name("WebsiteID");

	      echo "The previous session name was $previous_name<br />";
	      ?>
