Hi,

I need to make calls from webpage to external library written in C++ and display the result. Platform is Linux, Apache, PHP.

My current idea is to use PHP service which will call my library/program. I found that there are two possible ways to do this: 1) use PHP 'exec' function 2) write PHP extension

I am curious what works more effective? Faster? Less load the server?

I will probably need to do 4 calls per second, so I want to be as optimal as possible.

P.S. If you are aware of some other (more effective) way of calling C++ library or program from webpage, please let me know.

Thanks a lot,
Robusta
