posix_uname
(PHP 4, PHP 5)
posix_uname — Get system name
Description
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.
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
)
