I use php 5 on iis in a windows 2003 server machine.
I should start through php a dos program which should write an output
on disk,
but it doesn't. I can't write anything on disk this way. I used exec()
funtion and
similar, but they don't work. For example, this code

<?
$c = "dir c:\\ > c:\\inetpub\\wwwroot\\something\\foo.txt";
exec("$c");
?>

does not create the file foo.txt.

You should know that
- The programs are run, as i could check using passthru() rather than
exec(), but
they don't write on disk
- I have given permission to the internet user to write in the
directory where the file
should be created
- I have given permission to run the programs called by exec()
- I have allowed to run executable programs in iis

Anyone can ?

Thank you very much

Hi,

Why not:
exec($c);
??
Why add the ""?

Why should it?
Your 'command' doesn't make sense.
Type that into your commandprompt (without the extra \ of course): does
that create the file foo.txt?
No. Not here. ;-)

Or are you trying to execute foo.txt?


If you want to invoke a doslike shell, start your command at least with
cmd or command.
Did you check the reference?
Here you can find it:
http://nl2.php.net/manual/en/ref.exec.php

Be sure to read the first note for an example for dos.
(Which is actually chronologically the last note).
It contains an example with some advise about extra parameters.


You can also let PHP create a directory or file:
http://nl2.php.net/manual/en/function.fwrite.php
and
http://nl2.php.net/manual/en/function.mkdir.php

Hope that s.
