posix_uname

(PHP 3 >= 3.0.10, PHP 4, PHP 5)

posix_uname -- Get system name

Description

array posix_uname ( void )

Gets information about the system.

Posix requires that you must not make any assumptions about the format of the values, e.g. you cannot rely on three digit version numbers 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
)
