(PHP 4, PHP 5, PHP 7, PHP 8)
posix_uname — Get system name
说明
posix_uname(): array|falseGets 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.
参数
此函数没有参数。
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.
The function returns false on failure.
范例
示例 #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
