Basically the differnces of PHP version for Win9.x(PWS)/NT(IIS) and UNIX/Linux-Apache are :
Some file system functions are not supported in Win platform ...
It is due of the differences about security implementation between UNIX platform and Win/NT platform. So unlink(), chmod(), chgrp(), and some other won't work on Win/NT.
Bugs on external executing program.
In UNIX/Linux-Apache environment, you can do exec(), passthru(), system(), etc. But not in PWS/IIS ...
<?
exec("dir c:\ > \mytemp.txt");
print join("",file("\mytemp.txt"));
?>
The line first statement (exec) will run ok, but the second statement (print) won't be executed in IIS/PWS, the browser simply "hang" ...
