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!

Maybe this is not the best group to ask this question, but I don't know a better one. I'm looking for a *portable* program in C (I mean source code) to detect whether unaligned word access is: a. handled by the main processor (e.g. x86) b. not supported (e.g. Sparc running Solaris) c. emulated in software (e.g. Alpha running Linux) By "unaligned word access" I mean access to a 16-bit word

Hi, I'm looking for a reliable way of detecting the version of Windows that the ..NET framework is installed on, specifically the service pack. Currently, I'm using System.Environment.OSVersion and pulling the Major, Minor, Build and Revision properties out of that. However, e.g. Windows XP returns exactly the same values for no initial build, SP1 or SP2.

Hi, I'm writing a file browser, but I'm not sure how I could go about detecting the drives available on windows and linux systems (preferably using the standard modules if possible). I guess I could just try to list root on each letter of the alphabet for windows and see if it works, but that seems crude; besides, I want to know what kind of drive each drive/partition is (i.e. is it local and is it a harddrive or optical drive). Thanks,
