This is the reason I'm building Unit Tests. If you do a search, you will 
find many papers and resources on doing this. PHPUnit and SimpleTest are 
two major ones for PHP. If you are just starting out SimpleTest would be 
a better solution. SimpleTest has documentation and tutorials. Sadly, 
there isn't much else to help you, if you are still interested. You can 
read what the author of PHPUnit has to say about Unit Tests, by 
searching for him and reading his phpWorks Presentation.
