php system() and gpg

[l0ve2hat3]

I want to know if the following is possible:

 

a) interactive system() command.  I need to encrypt a file using "gpg -c myfile" but from command line you need to enter the pass phrase 2 times after calling that command. so something like:

system("gpg -c myfile"); system("test");system("test");

 

or

 

b) if there is an easier way to encrypt a file

 

[trq]

Plenty of ways to encrypt a file (See here).

 

Otherwise, take a look at expect.
