“PHP 7 moves full speed ahead”. 2018年1月31日閲覧。 “Recent versions of PHP have been part of the 5.x release series, but there will be no PHP 6. “We’re going to skip [version] 6 because years ago, we had plans for a 6 but those plans were very different from what we’re doing now,” Gutmans said.

“Resetting PHP 6”. 2018年1月31日閲覧。 “There have been books on the shelves purporting to cover PHP 6 since at least 2008. But, in March 2010, the PHP 6 release is not out - in fact, it is not even close to out. Recent events suggest that PHP 6 will not be released before 2011 - if, indeed, it is released at all.”
