PHP 5.3 - End of Life statistics

PHP 5.3 met its end-of-life in August 2014. It's been a good run for the most popular 5.x version (given by the several breaking changes introduced in PHP 5.4). How did the PHP 5.x universe looked a year ago? (using data from here as well as this presentation)

Version September 2013 (%) November 2014 (%)
5.0 0.1 % 0.1 %
5.1 2.2 % 1.3 %
5.2 40.2 % 21.4 %
5.3 51.7 % 46.9 %
5.4 5.7 % 25.1 %
5.5 0.1 % 5.1 %
5.6 - 0.2 %
5.7 - < 0.1 %

Conclusion? The much-delayed upgrade effort towards PHP 5.4 is well underway. The 5.3 market share previously fell by less than 2% for previous year but in the current year it fell by almost 5% while the adoption of PHP 5.4 has increased nearly 5 times.

Still, PHP 5.3 is deeply entrenched in its market share as the dominant version, something that will probably endure over the next year as both 5.2 and 5.3 sites slowly migrate.
