PHP get current server details

I am currently using PHP to write an enterprise-level CMS. I need to use PHP in the background to obtain the detailed information of the current server and related system parameter information. I have sorted it out and posted it here for future use.

Get the system type and version number: php_uname() (Example: Windows NT COMPUTER 5.1 build 2600)

Only get the system type: php_uname('s') (or: PHP_OS, example: Windows NT)

Only get the system Version number: php_uname('r') (Example: 5.1)

Get PHP running mode: php_sapi_name() (PHP run mode: apache2handler)

Get the pre-process user name: Get_Current_User()

Get PHP version: PHP_VERSION

Get the Zend version: Zend_Version()

Get the PHP installation path: DEFAULT_INCLUDE_PATH

Get the absolute path of the current file: __FILE__

Get the Host value in the HTTP request: $_SERVER["HTTP_HOST"] (return Value is domain name or IP)

Get server IP: GetHostByName($_SERVER['SERVER_NAME'])

Server IP that accepts requests: $_SERVER["SERVER_ADDR"] (Sometimes it cannot be obtained, it is recommended to use: GetHostByName($_SERVER['SERVER_NAME']) )

Get the client IP: $_SERVER['REMOTE_ADDR']

Get the server interpretation engine: $_SERVER['SERVER_SOFTWARE']

Get the server CPU number: $_SERVER['PROCESSOR_IDENTIFIER']

Get server system directory ：         $_SERVER['SystemRoot']

Get the server domain name (host name): $_SERVER['SERVER_NAME'] (Recommended to use: $_SERVER["HTTP_HOST"])

Get the user domain name:                 $_SERVER['USERDOMAIN']

Get the server language: $_SERVER['HTTP_ACCEPT_LANGUAGE']

Get the server web port: $_SERVER['SERVER_PORT']

Get the name and version of the communication protocol when requesting the page: $_SERVER['SERVER_PROTOCOL'] For example, " HTTP/1.0".

The above introduces PHP to obtain the current server details, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
