posix_uname - Get system name

SYNOPSIS
       array posix_uname (void	)

DESCRIPTION
	Gets information about the system.

	Posix requires that assumptions must not be made about the format of the values, e.g. the assumption that a release may contain three dig-
       its or anything else returned by this function.

RETURN VALUES
	Returns a hash of strings with information about the system. The indices of the hash are

	      o sysname - operating system name (e.g. Linux)

	      o nodename - system name (e.g. valiant)

	      o release - operating system release (e.g. 2.2.10)

	      o version - operating system version (e.g. #4 Tue Jul 20 17:01:36 MEST 1999)

	      o machine - system architecture (e.g. i586)

	      o domainname - DNS domainname (e.g. example.com)

	domainname is a GNU extension and not part of POSIX.1, so this field is only available on GNU systems or when using the GNU libc.

EXAMPLES
       Example #1

	      Example use of posix_uname(3)

	      <?php
	      $uname=posix_uname();
	      print_r($uname);
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [sysname] => Linux
		  [nodename] => funbox
		  [release] => 2.6.20-15-server
		  [version] => #2 SMP Sun Apr 15 07:41:34 UTC 2007
		  [machine] => i686
	      )
