You cant use pcntl_fork() within a web processes, what might be
useful:

[url]http://php.net/features.connection-handling[/url]

You'll be able to handle everything upto the point that you call
the pfpro->process function. Once that happens the payment will go
through. But if you are keeping track of results from the pfpro you
could flag the database that the user hit cancel.

What I would do instead would be to issue a ignore_user_abort(true)
and record the results in a database (since the output will not be
garenteed.) And not worry about what happens if the user does press
escape.

To be user friendly I would put a disclaimer, clearly visible, next
to the submit button 'Once pressing submit there is no turning
back', or something to that effect.


HTH,

I've not been able to find anywhere a good use of the pfpro
functionality in PHP. No where do any of the scripts ensure that the
script goes through it's full execution.

One person's solution was just to exec the pfpro binary in the
background, passing it the necessary arguments. This seems insecure.
I'd like to use PHP's pcntl_fork(), however, I read that using it in PHP
where PHP is an Apache module could produce unpredictable results.. Is
anyone using pcntl_fork with the pfpro stuff in a PHP compiled as a
module.....successfully?
