The title says it all. In a recent post I spoke about how I voted for the next version of PHP to be called PHP 7 over PHP 6.
In summary, the current brand of PHP is PHP 5.x, so the most logical next version would be PHP 6.x. However, PHP 6 once existed, although it was never formerly released. There are articles, blogs, and books available about PHP 6 and the then proposed changes. PHP 6 exists, but the release never happened – but it does exist. And that is what I based my vote on.
The vote has now closed and PHP 7 won, with a ratio of 58 votes for PHP 7 to 24 for PHP 6.
The PHP 6 RFC has the full vote breakdown.
