(PHP 4 >= 4.0.2, PHP 5)php_uname --

Returns information about the operating system PHP is running on

Description

string php_uname ([string mode])

php_uname() returns a description of the operating

system PHP is running on. For the name of just the operating system,

consider using the PHP_OS constant, but be

reminded this constant will contain the operating system PHP was

built on.

On Unix, the output reverts to displaying the operating system

information PHP was built on if it cannot determine the currently

running OS.

mode is a single character that defines what

information is returned:

'a': This is the default. Contains all modes in the sequence "s n r v m".

's': Operating system name. eg. FreeBSD.

'n': Host name. eg. localhost.example.com.

'r': Release name. eg. 5.1.2-RELEASE.

'v': Version information. Varies a lot between operating systems.

'm': Machine type. eg. i386.

Пример 1. Some php_uname() examples <?php echo php_uname(); echo PHP_OS; /* Some possible outputs: Linux localhost 2.4.21-0.13mdk #1 Fri Mar 14 15:08:06 EST 2003 i686 Linux FreeBSD localhost 3.2-RELEASE #15: Mon Dec 17 08:46:02 GMT 2001 FreeBSD Windows NT XN1 5.1 build 2600 WINNT */ if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN'){ echo 'This is a server using Windows!'; } else { echo 'This is a server not using Windows!'; } ?>

There are also some related

Predefined PHP

constants that may come in handy, for example:

Пример 2. A few OS related constant examples <?php // *nix echo DIRECTORY_SEPARATOR; // / echo PHP_SHLIB_SUFFIX; // so echo PATH_SEPARATOR; // : // Win* echo DIRECTORY_SEPARATOR; // \ echo PHP_SHLIB_SUFFIX; // dll echo PATH_SEPARATOR; // ; ?>
