There is no sure-fire way to ensure that your code will be upwards compatible with future PHP versions for time periods as long as 10 years. That is the case with virtually all other live language, including Java, C++ and Perl. If you want to take advantage of the new features in new versions, then the price tag attached is that there'll be sometimes compatibility breaking changes that you would have to live with. Typically it's a small price to pay for the extra features, but if you're not willing to pay it, you do have the option of not upgrading.
