As we embrace the changes that 2006 will bring to the PHP community, I can but only wonder about what is to become of PHP 5. Talk and debate over PHP 6 is already a hot topic, and despite being in a stable release for over 2 years PHP 5 has failed to see any significant kind of adoption rates, lingering at an astonishingly low 4.2%.
