    Detecting Windows or *ix?

    Hello group,

    I have a few PHP scripts that poll switches and routers via SNMP. Depending
    on the user, the scripts can be run from either Windows XP or *ix (FreeBSD,
    Redhat, etc)

    I am beginning to implement syslog() and openlog() in my scripts and there
    are some suddle differences in how PHP logs to event viewer in Windows and
    syslog in everything else. About the most reliable method I have found in
    detecting Windows is a simple check to see if $_SERVER['OS'] is defined,
    which returns "Windows_NT ". On Redhat it doesn't come back as defined at
    all, so that makes the code easy.

    I'm sure I am not the first one to attempt this, can anyone else share their
    experiences with this and maybe offer a better way other than checking for a
    predefined constant?

    Thanks,

    AJ Schroeder

      There are lots of ways. You could even look at the constant
      DIRECTORY_SEPAR ATOR to see if it's / or \ -- I have yet to find a *nix
      system that uses \ and a Windows system that uses /.

              Why? What's the problema with the constant PHP_OS ?

                  No problem... I guess I didn't know about it since I always ran the scripts
                  from Redhat.

                  I am using a the constants PHP_OS and DIRECTORY_SEPAR ATOR to check and see
                  what os the script is running from.

                  I also didn't know about php_uname(), so I am using that for something in my
                  scripts, too.

                  Thank you to all who responded, the suggestions really helped!
