posix_uname — Get system name
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.
Returns a hash of strings with information about the system. The indices of the hash are
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.
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
