Start compiling PHP extensions

I have code that is straight forward, but intensive. I would like to compile it into a PHP extension. What is the simplest / best practice for going about that?

I have a Java background, so writing the C / C++ code shouldn't be an issue. I would, however, like to avoid any pitfalls along the way.

It looks like a more arduous road then I though, especially with all the lovely C quirks.

The PHP Manual and this Zend article seem to cover quite a bit of ground in regards to writing PHP extensions.

You should try SWIG for generating wrapper for your source code, and then create your extension. It supports various languages like Java, C/C++ and makes it as simple as possible.
