    Srv OS compatibility and $_ENV

    I'm running PHP on my local WinXP box, but will host on *nix Srv.

    So I started to use and OS detect, something like (psuedo-code):
    if ( strpos($_ENV['OS'], "Win") === false ) { *nix } else { Win }

    but its not working right, and I wondered why.
    My OS looks to be set, as shown by WinXPset
    ditto for output from phpinfo()
    But the $_ENV global, looks like an empty array Array ( )
    whats the story ?

    Of course I've the incompatible versions of Apache/PHP: A2.2x and
    php5.1.x
    patched with php5apache2_2.d ll
    ( thats the only reason I didn't cry after installing 5.1.4 and then
    having 5.1.5 come out the next day ) It makes you wonder, what part
    of 5.1.x am I really using, if any

    my settings from phpinfo():
    Apache Version Apache/2.2.3 (Win32) PHP/5.2.0RC2-dev

      This can't be a good idea... I presume you need to use certain OS-dependent
      feature. Why don't you just check for that specific feature?

      Anyway, in the "Predefined constants" chapter I see PHP stores the value
      for you so you don't depend on environmental variables:

      Core Predefined Constants

      These constants are defined by the PHP core. This includes PHP, the Zend
      engine, and SAPI modules.

      PHP_OS (string)

      But the $_ENV global, looks like an empty array Array ( )
      whats the story ?
      Check the variables_order directive in "php.ini". There's also a comment
      about it in the file:

      ; - variables_order = "GPCS" [Performance]
      ; The environment variables are not hashed into the $_ENV. To access
      ; environment variables, you can use getenv() instead.

          Re: Srv OS compatibility and $_ENV

          I appreciate your comments and now know the skinny on this subject. I
          can use
          getenv()
          PHP_OS
          php_uname()

          I'm just very suprised that phpinfo() would report each ENV var, but
          these would not go into $_ENV
          Also, I did not see PHP_OS mentioned in the manual, but it appears to
          be a Standard part of the lang, and I saw quite a few references
          online.

              It can be found in:

              Main : Appendixes : List of Reserved Words : Predefined Constants

              I have the extended CHM version and I just typed "pred" in the index input
              box ;-)
