Thank you Jason... really!
Now I begun to let it work a little...
I found also, searching about the variables you said me in the sources, that
if I enable the configure option "--enable-discard-path", the variables are
not more needed, and the php begin to works!!!!! WOW!
So, I say it begins to work, because I've jumped into a well known bug, that
let alwasy displays "#!/usr/local/bin/php" at the beginning of the php
output... this can cause problems also with additional headers, that cannot
be sent...
is there a way to let this "#!/usr/local/bin/php" exit from php door...
isn't it ?!?
can be also this solved passing some variables ? Anyway, this
"#!/usr/local/bin/php" is displayed both from command line and from a "not
too friendly" webmin environment...
thank you very much,
prakash
