PHP Extension VS. PHP + COM

[vadik_g]

Hi, can anyone collaborate on the differences between PHP extensions versus PHP working with COM performances.

For example - in order to perform a specific task or set of tasks i may write a PHP Extension or create instances of some COM object.

Is there anyone who knows on his experience which one's better, faster, lighter or whatever.

Thanks, people.

I am sure you know, but if you use COM you are limited to Windows platform. an extension can be ported to any that php runs on.

Thanks for the post.

Yes, I do know that.
I assumed it was obvious. But i'd like to know the performance differences.
