PHP 6, the next major revision of the popular Web application development language, looms on the horizon and promises many changes. Learn what’s new and what’s obsolete and how to prepare your code for tomorrow.
It’s no secret that PHP has changed significantly since the earliest versions of PHP 4 were released almost a decade ago. Indeed, each major revision of PHP has required code changes, as language features were added, modified, and obsolete. Depending on your PHP code, PHP 6 will be no exception.
Although PHP 6 isn’t yet available as a pre-built package, you can download and install a development snapshot of PHP 6 now to check out the new features and verify your scripts remain functional. Since PHP 6 removes some backwards-compatibility features (which, in the long term, is a good thing), you should test your existing code thoroughly.
