There is a specific thing called PHPUNIT.  Is that what you are asking about?

If not, then maybe this article about test-driven development will help.

The general idea about unit testing (in the case of the article, it is about testing a regular expression, one tiny unit of a much larger script set) is that if we make each of the pieces of the puzzle well-defined and correct we are more likely to complete the overall task quickly and accurately.
