Well.. I would kinda say it's a windows console app.. Normal windows apps doesn't have the main() function, but instead the windows specific winmain().. Dos apps used main() as well.. Now, windows finds the starting address of the program somewhere at the end of the file I think (wild guess though), while dos just runs it from the beginning or something like that.. They use different starting addresses anyway.. Meaning that one .exe file could accutually be a graphical windows app as well as a real dos console app.. I cannot confirm this, but I have a slight feeling I saw something like that in some norton app to make backups of drives/partitions.. Dos 7 is 95, 98 and 98 SE afaik.. 8.0 is windows Me.. Now: > - Would the filesystem functions work? Yes.. well, unless PHP uses the windows optimized versions, but that doesn't exist is linux so probably not a problem.. > - Would TCP/IP connections work the same? No.. I don't think TCP/IP works at all in DOS.. There's no winsock there.. Accutually, I don't even think there's dlls.. > - Would basic int / string / float / etc. variables be stored in memory the way that they are in Windows? Yes, as long as you use an x86 computer newer than a 80386, and a C implentation that doesn't do anything wierd with it.. > - Would system calls have input, output, and / or error redirection? Dos includes STDIN, STDOUT and STDERR yes.. At least dos 3.x did.. :p > - Is shared memory managed the same way as in newer versions of Windows? Probably not.. 2 apps can't really run at the same time in dos (not like in windows anyway), so shared memory probably isn't even a part of the OS.. -- // DvDmanDT MSN: dvdmandt¤hotmail.com Mail: dvdmandt¤telia.com <tg-php@xxxxxxxxxxxxxxxxxxxxxx> skrev i meddelandet news:E1CtpjY-0006fy-SK@xxxxxxxxxxxxxxxxxxxxx > I think people get confused when they talk about "Windows apps" and such.

So then you ask yourself, "Why does PHP need a GUI if we're only trying to run it in command line mode?". I guess one answer is that you really DONT need Windows, but in the evolution from DOS to Windows there were some things done that were never added to the older DOS-only systems that PHP requires. > > It's probably more accurate to say that PHP, even command line, is a win32 app. This means that it's using some win32 calls/functions/whatever that you can't get in a DOS-only environment.
