Hi (love your avatar/image),
if you transposed the syntax exactly from your httpd.conf then
you'll see that you are using forward slashes instead of
backslashes. remember, win32 OS's used to ride on top of that
old MS-DOS, which uses backslashes.
so the reason apache is spitting mud is because it is not seeing
the \path\to\php4apache.dll because you have the
/path/to/php4apache.dll incorrectly specified... perhaps?
aside from that i can't tell you... i've never installed php onto
win32 apache.
just a shot in the dark, so i hope that helps! 🙂
