GnuPG and PHP

[php@oxyd.fr]

Hi,

I'm trying to set up a script to send PngPG signed mail with PHP.
I succeed in sending encrypted mail but it's not working with signed mail.

--------
file.txt = original file / crypted.txt = crypted file
--------
system("/path/bin/gpg --encrypt -ao /path/crypted.txt /path/file.txt");

this command works fine but i need to sign ...

--------
file.txt = original file / crypted.txt = crypted file / pass.gpg = file 
containing the passphrase
--------
system("/path/bin/gpg --clearsign --passphrase-fd 0 -
ao /path/crypted.txt /path/file.txt < /path/pass.gpg");

this one is NOT working... 

Can s/o help me... ?
 
Thanks
