posix_uname
(PHP 4, PHP 5, PHP 7, PHP 8)
posix_uname — Get system name
說明
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.
參數
此函式沒有參數。
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.
