posix_uname

    (PHP 4, PHP 5, PHP 7, PHP 8)

    posix_uname — Get system name

    Description

    posix_uname(): array|false

    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.

    Parameters

    This function has no parameters.

    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.

    The function returns false on failure.

    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
)

    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
    )
