posix_uname

(PHP 4, PHP 5)

posix_unameGet system name

说明

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.

返回值

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.

范例

Example #1 Example use of posix_uname()

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

以上例程的输出类似于:

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