First of all, do you have permission to issue the exec() function? Many
shared systems have it disabled for security reasons.
If you do have permission, is the php executable available to you?
Again, on a shared system, it may or may not be.
Finally, if it is available, the second script is going to be executed
in the cli environment, not the web. This means the session_start()
will fail, as there is no web server involved (well, it may not fail -
but it won't do anything). And its output goes to stdout, (which is fed
back to the second parameter of exec(), which you are not using, so it
is thrown away), not to the web.
IOW, what you're trying to do is definitely not common, and probably not
the right way to go about things.
What is it you're really trying to do?
