I know this is a simple question, but I can’t for the life of me get it to work. If I log in to my server via SSH (linux) and type in : /home/username/public_html/x/foo.cgi f=subscribe l=list e=abcd@gmail.com the script runs perfectly. However, if I try to run the script via PHP by the likes of : shell_exec("/home/username/public_html/x/foo.cgi f=subscribe l=list e=abcd@gmail.com"); nothing happens.

Can anyone point me in the right direction?

Thanks ahead of time!

    “Nothing happens” isn’t a very descriptive error message. Nevertheless, three possibilities come to mind:

    1. Differences between the server-hosted environment versus the shell environment.
    2. Your server or hosting site may have disabled shell_exec or other functionality.
    3. You may need to be running PHP as the same user you SSH’d in as (or otherwise get the correct permissions).
    4. Some other piece of the stack are in disarray due to mis-configuration or misuse.

    Take your pick. Check your logs. Make sure you don’t leave any holes available for attackers to get in.
