LEARN ABOUT PHP

php_uname

PHP_UNAME(3)								 1							      PHP_UNAME(3)

php_uname - Returns information about the operating system PHP is running on

SYNOPSIS

       string php_uname ([string  $mode = "a"])

DESCRIPTION

       php_uname(3)  returns  a  description  of  the  operating  system PHP is running on. This is the same string you see at the very top of the
       phpinfo(3) output. For the name of just the operating system, consider using the PHP_OS constant, but keep in mind this constant will  con-
       tain the operating system PHP was built on.

	On some older UNIX platforms, it may not be able to determine the current OS information in which case it will revert to displaying the OS
       PHP was built on. This will only happen if your uname() library call either doesn't exist or doesn't work.

PARAMETERS

	      o $mode
		-$mode is a single character that defines what information is returned:

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

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

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

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

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

		     o 'm': Machine type. eg.  i386.

RETURN VALUES

	Returns the description, as a string.

EXAMPLES

       Example #1

	      Some php_uname(3) 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:

       Example #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;	// ;
	      ?>
