posix_uname

posix_uname

(PHP 4, PHP 5, PHP 7)

posix_uname — Get system name

Description

array posix_uname ( void )

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 digits 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

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

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

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

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

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

  • 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()

<?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 )

← posix_ttyname
