posix_uname

(PHP 4, PHP 5)

posix_uname — Get 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
)

Or, a simpler way to do that: <?php print_r(posix_uname()); ?> Should print something like: Array ( [sysname] => Linux [nodename] => vaio [release] => 2.6.15-1-686 [version] => #2 Tue Jan 10 22:48:31 UTC 2006 [machine] => i686 )

A simple example of how to loop thru and display the results of the posix_uname() function... <?php foreach(posix_uname() AS $key=>$value) { print $key .": ". $value ."<br>"; } ?> The procedure above should return something similar to the following results: sysname: Linux nodename: node1 release: 2.4.26 version: #6 Mon Jun 14 19:07:27 PDT 2004 machine: i686
